CMPL v.2.0

CMPL has been (almost) completely redeveloped and comes with a lot of new functionalities.

	Examples are improved syntax, logical constraints, native support for SOS, the opportunity 
	for users to write their own functions in CMPL and much more. Furthermore, 
	CMPL has been extended with a new interactive interface to Excel. A user can read sets and 
	parameters into the cmpl model and write results directly into an open excel file. 
	This feature is availbale on Windows and macOS. 

	In addition, pyCmpl, jCmpl and CmplServer have been revised and  extended. For example, 
	pyCmpl is now fully ported to Python 3. Python2 is no longer supported.
