Returns the size in words of ship type. Inputs are the fragment table, the number of elements in the fragment table,
and the number of words that make up nationality.
The number of fragments (words) in a ship name dictate the possible sizes of ship type. If nationality takes one fragment,
and ship type takes four fragments, then the minimum number of fragments in a composite ship name is:
5 = 1 (nationality) + 3 (ship type) + 1 (ship name) (same as 4 fragments (words) after nationality)
This function starts at the longest possible series of fragments that might be ship type. This order is important becuase
some ship types might begin with similar fragments: 'ship' and 'ship of the line'. Starting with the least possible
series of fragments (1) would find 'ship' and make 'of the line' part of the italicized name.
Returns 0 if there is no recognizable ship type.

This function applies correct styling to ship and ship-class names. These names are, for example, ship-article titles
used by templates {{navsource}}, {{Infobox ship begin}}, where the article title is to be rendered with proper
styling.
This function requires one argument:
|name= (required): a name is required; if missing or empty, this function returns an error message (may or may not be visible depending on where it is used)
used in {{infobox ship begin}} to provide a value for {{DISPLAYTITLE:}} and to provide a value for |infobox caption=
{{#invoke:WPSHIPS_utilities|ship_name_format|name={{PAGENAME}}}}
Optional arguments to support {{infobox ship begin}}:
|dab=none – displays ship name without parenthetical disambiguator; use when |infobox caption=nodab
|sclass=2 – for ship classes only; displays class name without italics (parameter name is loosely similar to {{slcass2}} which does the same thing); use when |infobox caption=class
|adj=off – for ship classes only; displays class name as a noun (no hyphen, no ship type); use when |infobox caption=class
Arguments are passed in a table.
to call this function locally:

args = {['name=name'], ['dab']=dab, ['sclass']=sclass, ['adj']=adj, ['showerrs']=showerrs};

This function is the external interface to do_ship_name_format().
The function requires one parameter:
|name= (required): a name is required; if missing or empty, this function returns an error message (may or may not be visible depending on where it is used)
used in {{infobox ship begin}} to provide a value for {{DISPLAYTITLE:}} and to provide a value for |infobox caption=
{{#invoke:WPSHIPS_utilities|ship_name_format|name={{PAGENAME}}}}
Optional parameters to support {{infobox ship begin}}:
|dab=none – displays ship name without parenthetical disambiguator; use when |infobox caption=nodab
|sclass=2 – for ship classes only; displays class name without italics (parameter name is loosely similar to {{slcass2}} which does the same thing); use when |infobox caption=class
|adj=off – for ship classes only; displays class name as a noun (no hyphen, no ship type); use when |infobox caption=class
Other optional parameters:
|showerrs=yes – marginally useful; can display error messages if the module invocation is not buried in a template
Values from the above parameters are placed in a table and that table passed as an argument in the call to do_ship_name_format().
do_ship_name_format() returns two strings: a name and an error message. If do_ship_name_format() could format the name, it returns the formatted name and
an empty string for the error message. If it could not format the name, do_ship_name_format() returns the original name and an error message.
Formatting of the error message, in response to |showerrs=yes is the responsibility of the calling function.

Assembles an error message, the original parameter value and, if appropriate a category. The error message precedes
the existing value of the parameter. If the first non-whitespace character in the parameter is a '*', set prefix to
a '*' and sep to '\n'. For line-break lists, set prefix to empty string and sep to '<br />'.
Category is appended to the end of the returned value only for pages in article space.
Inputs:
prefix – a string of characters that precede the error message span; typically '' and '*'
message – the error message to be displayed; goes inside the span
sep – a string of characters that separates the span from the parameter value; typically '\n' and '<br />'
param_val – the unmodified parameter value
showerrs – a boolean, true to display the error message text

Mediawiki:Common.css imposes limitations on plain, unbulleted lists. The template {{plainlist}} does not render this correctly:
{{plainlist|
*Item 1
*Item 2
**Item 2a
***Item 2a1
**Item 2b
*Item 3}}
The above renders without proper indents for items marked ** and ***.
If the list is not wrapped in {{plainlist}} then the above list is rendered with bullets which is contrary to the Infobox ship usage guide.
This code translates a bulleted list into an html unordered list:
<ul style="list-style:none; margin:0;">
<li>Name 1</li>
<li>Name 2</li>
<ul style="list-style:none">
<li>Subname 2a</li>
<ul style="list-style:none">
<li>Subname 2a1</li>
</ul>
<li>Subname 2b</li>
</ul>
<li>Name 3</li>
</ul>
There are rules:
1. The parameter value must begin with a splat but may have leading and trailing whitespace.
2. Each list item after the first must begin on a new line just as is required by normal bulleted lists.
3. When adding a sublevel, the number of splats may increase by one and never more. This is illegal:
*item
***item
When any of these rules are violated, unbulleted_list() returns the original text and adds the article
to Category:WPSHIPS:Infobox list errors. Error messaging in this function is somewhat sketchy so they are
disabled. After initial adoption, better error messaging could/should be implemented.
This function receives the content of one parameter:

support function for infoboxen functions
This function handles all infobox ship parameters that are 'line items' (label followed by value) because all
of these sorts of parameters are rendered with exacty the same formatting.
params_t{} is a table of tables where the params_t{} keys are the template's parameter names. The params_t{}
values are sequences where [1] is an index number that defines where in the rendering the label/value pair is
positioned and [2] is the label that will be rendered when the parameter has a value.
This indexing is used because params_t{} is not a sequence and because pairs() does not necessarily return the
'next' k/v pair.
This function spins through params_t{} and writes html for parameters that have assigned values into temp_t{}
according to the 'index' value in the associated sequance table. When parameters are missing or empty, this
function writes an empty string into the associated location in lines_t{} so that lines_t{} can be concatenated
into a string value that is returned to the calling function.
args_t is the arguments table from the template frame.
