2015-06-23	Changed name of files to reflect that the adder and the shifters are now not ↵	Joachim Strömbergson
	specifically working on 32-bit operands. HEADSUP: This breaks builds that use the old file names.
2015-06-23	Made the adder and shifters words size generic. Updated the montprod and ↵	Joachim Strömbergson
	residue to use the generic adder and shifters.
2015-04-21	Update of modexp to include more of the integration of residue calculator. ↵	Joachim Strömbergson
	Update of shl and shr to simplify code. shl and shr could be replaced by functions.
2015-04-13	Adding initial versions of rtl for modexp. Montgomery multiplication works ↵	Joachim Strömbergson
	for 8192 bit operands. Modexp can build, but lacks proper control and residue generator. Memories has been tested to match block memories in Xilinx and Altera FPGAs.
