This is an experiment to see what is required to consolodate all of the myriad {{lang-xx}} templates
and their subtemplates into a single module with a data table
{{lang-es}} has parameters:
{{{1}}} text - required
{{{link}}} or {{{links}}} defaults to 'yes'
{{{lit}}} literal translation
{{language with name}} has parameters:
{{{1}}} iso language code - required
{{{2}}} language name in English - superfluous?
{{{3}}} text - required
{{{4}}} or {{{lit}}} literal translation
{{{link}}} or {{{links}}} set to 'no' disables '{{{2}} language' wikilinks
{{{rtl}}} passed through to {{lang}}
{{{nocat}}} passed through to {{lang}}
{{lang}} has parameters:
{{{1}}} iso language code - required
{{{2}}} text - required
{{{rtl}}} if set to any value, set rtl="rtl" attribute and inserts ‎ after the </span> tag
{{{nocat}}} if set to any value, disables categorization
How it works now:
1. {{lang-es}} receives text as {{{1}}} to which it adds italic markup, sets |links to {{{link}}} or {{{links}}} or yes, sets |lit to {{{lit}}}, and calls {{language with name}}. {{{rtl}}} ignored for this example
2. {{language with name}} renders [[Spanish language|Spanish]] ({{{links}}} not set) or Spanish ({{{links}}} set) and calls {{lang}}
3. {{lang}} wraps the text in the <span lang="es">text</span> and adds categorization

Returns true if argument is set; false otherwise. Argument is 'set' when it exists (not nil) or when it is not an empty string.
This function is global because it is called from both this module and from Date validation

Makes a wikilink; when both link and display text is provided, returns a wikilink in the form [[L|D]]; if only
link is provided, returns a wikilink in the form [[L]]; if neither are provided or link is omitted, returns an
empty string.
