hi
all prints are working
parsing also working, some(eps, ambiguous etc) checks left
- Added code for removing left recursion
	- both indirect & direct
- Change in the stringstream usage in the code for firstOf,
	populateFollow & nullable
	- using substr method to get the remaining tokens
	- TODO if this doesn't work then use the find_first_of

- TODO
	- Integration & debugging compile time & runtime errors
