Module:TOCstyle

--[[
	This module (tentatively) implements {{TOCstyle}}
	Intended invocation method: {{#invoke:TOCstyle|toc}}
	Normal invocation via application of Template:TOCstyle

	The intent of this module is to provide a higher-level "styling" facility to aid in the creation of standard tables-of-contents
	(TOCs) on (initially) the English WikiSource in a reasonably flexible fashion. To this end there are a number of internal
	configuration tables (future task: separate these into a configuration helper module if possible?)

	All internal variables obeying the naming convention "...Tags" (e.g. "outerTags") designate two-element tables of strings
	containing HTML tags which shall be used to "wrap around" various output components. The first element content will open any
	required construct and the second element content will provide the necessary closing tags for that construct.
