Test_Import_NodeShape: Change from importing static method to importing class.
Added Format2:  Copy of Format for development.
Experimenting with importing a compiled enum (initially problem using compiled enum because enum constructors had changed between Groovy v1.8, installed with Freemind, and v2.2, installed as stand alone, which was used to compile the enum.  Problem fixed by upgrading version of Groovy running in Freeplane).
Test_Cloud: Experimenting with how to set or clear clouds in mind map.
