Moved fixed point function to cpp file
Switched to using C++11
Enabled 32 bit warning printing
Fixed bug in INA219 register writing
More files for 32 bit warning printing
project file changes for new FIxedPoint.cpp file
Changed how timer event objects are defined
Added a new TextLCD command to clear one line.
Added ButtonSet object to manage multiple buttons with one event.

This is implemented with a variadic template, which seems to generate an awful lot of code, so I will probably change that
Fleshed out menu object
