- Re-organized source code files into a ‘grbl’ directory to lessen one step in compiling Grbl through the Arduino IDE. - Added an ‘examples’ directory with an upload .INO sketch to further simplify compiling and uploading Grbl via the Arduino IDE. - Updated the Makefile with regard to the source code no longer being in the root directory. All files generated by compiling is placed in a separate ‘build’ directory to keep things tidy. The makefile should operate in the same way as it did before.
