 * ExcelToFromCanvas.jar
 * 
 * This program copies date from Excel to Canvas or to Excel from Canvas. Upon 
 *  starting, the program prompts for an Excel file. If that Excel file exists, 
 *  then this program will copy data from that Excel file to Canvas. Otherwise, 
 *  if that Excel file does not exist, then this program will create a new Excel 
 *  file, and copy data to that Excel file from Canvas. This program uses 
 *  ApachePOI or OpenCSV to read/write to Excel files and uses Selenium for web 
 *  browser automation. 
 *  
 * This program has a "do anything" license.

ExcelToFromCanvas.jar, chromedriver, and config.txt should all be placed in the same directory that you are running the .jar file from.
	The program saves your previous configuration in config.txt. 
	For chromeDriver
		If using Windows, then only need chromedriver.exe 
		If using Mac,     then only need chromedriver_mac
		If using linux 32,then only need chromedriver_linux32
		If using linux 64,then only need chromedriver_linux


If the program doesn't work, then I will recommend running it in the terminal or
	command window for debugging information. Some possible reason may be that
	the chrome web driver is not executable 
	(in which case, do "chmod +x <chromeDriver>") or your chrome is outdated.
