match html to spacebars template algorithm

html_match_spacebars.js

		templateMatches = templatesWhoseFirstLineMatchesNode(node.shift(), templates, lineIndex),
		isMultipleMatches = templateMatches.length > 1;
	
	//nodes has first element removed, and templateMatches is reduced to those that match on the first line
	if(isMultipleMatches)  return findMatchingSpacebarsTemplate(nodes, templateMatches, lineIndex + 1); 
	else return templateMatches.pop(); //we have found the one matching template! yay!!
}

		//obviously we will do more advanced parsing here, but the idea is it's not that complex
		return template.lineToString(lineIndex).indexOf(node.openingTagToString()) > -1;
