rosco pekolt / Mbed 2 deprecated nRF51822

This code is tho put in evidence a BUG in the TIMER implementation on Nordic TIMER bug nRF51822. This Example was created for plateform nRF51-DK. Led 2 will stop blinking (crashed main) when user button is pressed several time. User button start an interrpt, the interrupt set a tickker timer 200ms laterthe change LED 1. Meanwhile in the main loop LED 2 is changing state. You will see taht after a chile LED2 will sotp blinking meaning that program is crashed.
