API CHANGE: AddAtom method of Ref is now AppendAtom.   Also, Modified Ref interface, split it in smaller ones
Started changing the API to have Vecs instead of Rows, and other small things. Gochem is broken in this commit and doesnt past the tests.
API BREAK: functions NewCoords now create matrices with 3 columns, and take only one parameter. A new function ZeroVecs creating 3-cols array is provided. New functions AddVec, SubVec, SomeVecs, SomeVecsSafe  and ScaleByVec  are to be used instead of the *Row equivalents when working with coordinates.
API BREAK: Rad2Deg and Deg2Rad functions are replaced by multiplicative constants of equal names. Other unit conversion constants are added
bug fix
Interface to Reduce passes the test
Interface to Reduce passes the test
the test works and so does a proof of concept for a PyMOL plugin
MINOR API BREAK: Order of last 2 parameters have changed in RamaPlot.  Fixed a bug in RamaPlotParts
Minor changes to RamaPlot and RamaPlotParts functions, some additional info added to README
DecodeJSONMolecule should now handle several frames (not tested)
removed secondary structure field from Atom. Since it is expected to change from state to state, it  is better to have it as a separate slice or map.
transition commit
The interface with reduce is working correctly but it writes to disk. I have not managed to give reduce the PDB directly with a pipe
added back images
