Browse Source 
Currently working:
 - Connect/Disconnect, Read CPU info
 - CMM Script generation and T32 startup via cmake (make runt32)
 - Read/Write Register, Read Program Pointer
 - Read/Write Memory
 - Single Breakpoint
 - Setting Memory Breakpoint

TODO:
 - Fix mock aspect for T32_GetRam.
 - Fix Thumb2 bit in function addresses from ELFReader
 - Evaluate memory breakpoint hit
