- Fixed problems with mult
- Addeded method to calculate multiplicative inverse
- Fixed a bug in mod163 function
- Fixed a bug in function getBit(...)
- Implemented ECC
	- Added function isNeutral to check wether a Point is the neutral Element
	- Added function dbl to compute R = 2P
		- Function still buggy (hangs in some cases that may be related to multiplicative inverse
	- Added function addP to compute R = Q + P
	- Implemented method mult_scalar using Double-And-Add algorithmO
