Title: Ics

I've pretty heavily modified the ICS calculator (Not quite sure what changed from ICS to JB - I started before that). You can quickly test it out here: https://play.google.com/store/apps/details?id=com.android2.calculator3

New features:
-History (as a dropdown)
-X,Y graphing
-Matrices
-Hexadecimal and Binary support

and a lot more. The package name changed so I could put it on the market.

I hope I'm doing this right. I'm not sure how I'm supposed to be sending my changes.
