Example to go with my modified GPS library

Dependencies:   GPS mbed

Fork of GPS_HelloWorld by Simon Ford

added platform

I tested the GPS program. I found any bug. 1. The "tasks" variable not exist in printf 2. When component name output using terminal window, it does not show the component name.

And I added the tested platform
