A simple Hello World program, to demonstrate the current problem with the dm_board_config.h file - if it is in its normal place, the root directory, the project will not build, while if I copy it to the DMSupport subdirectory, the project builds OK.

Dependencies:   DMBasicGUI DMSupport

Demonstrates the current problem with dm_board_config.h - the project will not build with this file in its normal place, the root directory, but builds OK if I copy it to the DMSupport subdirectory.
