Remove all files that have been separated into a new library 'objectlib'
Prepare the 'objectlib' package to be separated into a library module
Refactoring: split the 'objects' package into two, 'objects' and 'objectlib'.The point: we're going to need to move the 'objectlib' stuff into its own library module, and that's because we're going to create a new app module which needs access to it.
Move actual solving the object to PreRender.
(before we had a 'solveObejct()' in preRender already, but that one just starts the Solve Effect!)
New 'tutorial' activity.
Rename some classes.
Convert the PostRender to a PreRender, called before we render.This makes more sense as this way things are prepared for the very first render.
More support for the 3x3x3 Solver: more of the actual 3x3x3 solver mechanism.
