Rigado / mbed-src-bmd-200

mbed-src updated for BMD-200 evaluation board. Just pin numbers are updated.

Fork of mbed-src by mbed official

Replacement for the "mbed" or "mbed-src" library when using the BMD-200 Evaluation kit. This library only remaps the pin names (i.e. LED1 points to p0.01 instead of p0.18, etc) as used by the BMD-200 Evaluation board (select the nRF51822_mkit platform). All other code is untouched.
