/**
*	PARSER.H
*	~PARSER CLASS~
*	CREATED BY JARRETT S. JOHNSON
*	UPDATED DECEMBER 2017
*	YANG ZHANG LABORATORY
* 	UNIVERSITY OF MICHIGAN, ANN ARBOR CAMPUS
*	Desc: C++ Parser class to manage parsing files into simple C/C++ types and objects
*	Note: Use GCC versions 5 and newer
*	Note: std::deque preferred over std::queue due to std::queue's lack of .clear(), and inability to
*		be used in ranged-based for's.
