This is the unit tests for the class VersionNumber.

VersionNumber has no specification beyond its implementation. There are few important elements to be noted:

        * Does NOT support 0 in versioning, i.e. 0, 1.0, 5.0.843, etc.
        * Does support empty version from a string, e.g. '', or a collection, e.g. #().
        * VersionNumber>>fromString will ignore trailing numbers if not sperated by a dot.
        * VersionNumber>>next advances the minor number (last value), without turn over.
        * VersionNumber>>branchNext creates a sub-minor version number, e.g. 1.5 becomes 1.5.1.
        * VersionNumber>>previous reduces may truncate the number, e.g. 9.1 -> 9, 1 to empty.
        * An annoying character improperly displayed as "" should be removed from source code.!
