	This function is intended to emulate the PHP getEnv function

	It has other added options like HTTP_ROOT and RELATIVE_ROOT.
	RELATIVE ROOT is an alternative to DOCUMENT ROOT as we do not 
	want to show anyone the DOCUMENT ROOT in our scripts.
	
	If you make any amazing addition and improvements to this function
