Define set of learning tools to be able to understand RON faster and easier

[mputz86]

Define (and later implement) a set of learning tools, which in general should help to visualize how RON works and see the effects of changes easily.

For example:

• Round trip for RON: start with raw RON ops, let them edit, see the output.
• Print out StateFrame/ObjectState with colors for different UUIDs (to easily spot different replica, ...)
• Visualize the compression of RON ops from: a) Closed Op representation to b) Open Op representation to c) abbreviated Atom (in Text) and, finally, to d) compression in Frames (chain compression)
• Visualize merging: e.g. with time-traveling possibility, to see intermediate states of a merge.

Great idea for a side project!
