/*
	DefaultDataEntry is sort of a stand in for a spreadsheet, it contains a series of arrays
	which hold each kind of data, line by line as they are passed (and parsed) from the datachecker.
	DefaultDataEntry also keeps trak of which lines had errors, and can return data either by
	entry (line) or by catagory (array), size of arrays are determed when datachecker is
	instantiated.  Actual assignment of color, catagories, etc is made by net assembler
	during conversion to nodes
