templatedata services for other modules. 
template-invokable method, testTemplateData() for testing purposes only.


Methods:
	_readTemplateData( templateName )
		internal method. receives a page name, tries to see if it exists, and contains valid templatedata.
		if there is valid templatedata, it extracts the json, and uses mw methods to return a lua table containing the data.
		otherwise, returns nil

	readTemplateData( templateName )
		gets a pagename or an array of names, and cycles through them, trying to get templatedata from this file.
		when it gets a valid structure, it returns it, otherwise keep cycling.
		templateName can be a string or a table. if it's a string, it's assumed to be a template page name, 
		where valid templatedata exists in the page or in a subpage whose name is in the local variable docSubPage

	testTemplateData( templateName ): for testing. invokable from template. dumps templatedata lua object, using mw.dumpObject.
	
	compat( templateName ): backword-compatability for validation module expecting subpage in specific structure.
