-# A lightweight module to read legacy hoomdxml files.
-Provides basic routines to read and extract information included in hoomdxml files.  While there are other packages do support reading hoomdxml files, they do not parse all sections of the file. This code will also perform grouping of atoms into molecules based on connectivity.  The module also provides routines to enable conversion to an mbuild ``Compound``.
