 /****************************************************************************************
	Created by Alex Gonzalez
	Date: July 8th 2009
	Version: 1.0
	
	Revisions:
		none
	
	Description:
		Creates a glossary search engine with alphabetized categorization. Keywords
		are highlighted with the class ".glossary_match" for custom styles.
		
		NOTE: The glossary has to be instantiated before any actions are called.
		
	Usage:
		--without callback--
		var myGlossary = new glossary("db_file.xml", "#target");

		--with callback--
		var myGlossary = new glossary("db_file.xml", "#target", function (){
			alert("Loading Complete!");
		});

	Functions:
		<instance>.loadXML(xmlDBfile, callback)
			Reloads an XML glossary database.
		
		<instance>.setFormat(entryTag, termTag, definitionTag, matchTag)
			Change the format for the output.
		
		<instance>.search(query, callback)
			Searches the database for keywords in a query.

		<instance>.showAlpha(letter)
			Retrieves all terms that begin with the letter supplied in the parameter.
			
		<instance>.useAppend(bval)
			Set append option on all ouput instead of replace.
	
	Classes Used:
		.glossary_error
			Appears when an error is encountered.
		.glossary_not_found
			Appears when a result is not found.
		.glossary_match
			Appears when a search is performed.
