converted the regex patterns to a wildcard for the group names
incremental commit
first cut at building the list difference tree
now builds value tree and reference tree
first rough working version of the object difference ignoring list order (for 2D and less, needs more work for 3D and higher)
clean code; added unit tests for Group class
added additional test items
added test cases for ignoring list order
clean-up test cases a bit
first working version of reording 3D arrays
