Added navigation drawer and a "root view" for testing purposes. Currently, it breaks a few things, so I'm pushing it into a seperate branch.
Attempting to convert into a different Navigation Drawer
Navigation Drawer no shows a Toast to show what it's doing.
Currently, selecting one has no usability.
Clicking on the application title will now trigger the navigation drawer.
Test commit
Added a "home" view. It shows a basic TextView that will soon explain how to use and navigate the application.
Added functionality for the A x B button. More soon to come.
Added functionality for all buttons located in the "Binary Operations" view.
Changed logo. Home view now shows a small introduction. Will later show the user a small how-to-use tutorial.
Merging the testing branch now that core functionality is present and new functionality is functioning properly.
