Wake-up timer library to wake from deepsleep/power-down

Dependencies:   LPC1114_WakeInterruptIn

Dependents:   LPC812_Sleep_HelloWorld KL05Z_DCF77_RTC_Clock LPC1114_data_logger mBuinoBlinky ... more

Issue: RTOS and L476RG

Does this library work with the mbed-rtos? I have added a thread idle callback that calls deepsleep. It doesn't seem to want to wake up.
