// LineGraphEditor.h
// Model:		Program parses CSV file and creates a table of values
//				Modified table of values is saved back to the CSV file 
//
// View:		The table of values is displayed to the user as a line graph
//				The line graph actively reflects changes to data
//				The numerical data is displayed in editable databoxes
//
// Controller:	The user can manipulate the databoxes within the window
//				The user can save the current file
