Šolski center Kranj / Mbed 2 deprecated 002-ioconfig-out

Program which demonstrates the usage of the IOCONFIG & GPIO peripherals. Program only blinks the LED based on the primitive delay function which only makes microprocessor busy for some time. Source code is split - we keep register definitions in header files away from the main source file.
