Write-in Module

The writing module code has been written and today I met with Javier to test the data on the evote prototype device. While testing we found errors with pointers , but this was fixed by reviewing how to work with pointers in C.
The write in screen currently supports keypad navigation and selection of letters.
Errors have been seen when typing letter and backspaces and when moving through the alphabet (the selected action happens twice).
The write in module successfully returns the array of the write in information.
