+Using object oriented programming, the main classes in WrightTools are children of h5py classes,

WrightTools takes a unique approach to representing CMDS data in array format, nick-named
``semi-structure'', that allows for greater flexibility in representing CMDS in different
coordinate spaces. %
WrightTools is written to be used in scripts and in the command line. %
It does not have any graphical components built in, except for the ability to generate plots using
