Version 0.6

Nearly all non programming functionality of the HP41CV is now implemented. Only ISG and DSG test, DEG, GRA and RAD angle modes and FIX, SCI and ENG formatting modes are missing. All math functions are moved to separate class to prepare for a programming mode. The application is tested on a HTC Desire (android 2.1) and in the HVGAA2.2 simulator (android 2.2).
