2015-04-27	Updating modexp core to v 0.50. This version contains a working core that ↵	Joachim Strömbergson
	can perform sign and verify with big keys/values. The core builds ok in Altera and Xilinx FPGA tools. This commit also includes a new testgenerator capable of generating testbench for modexp with autgenerated test data of different lengths. The README has been updated with status and implementation results in for different FPGA devices.
2015-04-21	Fixed incorrect types.	Joachim Strömbergson

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.
2015-04-20	(1) Modexp with better API. (2) Adding working residue module. (3) Adding ↵	Joachim Strömbergson
	new shift32 with carry module needed by the residue module.
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.
