/* 
	As a way to further the separation of layer abstractions, it is good practice to 
	never use inline functions (i.e. onmouseover="someFunction();") within html tags.
	Instead, get used to using the DOM to modify identified elements.  The fuction, 
	getElementsByClassName, facilitates the objective of selecting multiple elements
	with the same function purpose to modify or add dynamic behavior.  Adding a queue
	data structure adds a first-in-first-out organizing priciple for executing function
	calls for a given event
