 22  """The general interface of MBDyn elements. For each element group, 
 23  a general class is defined in that module. However most of 
 24  the elements do not have yet any SWIG interface. In case of  
 25  development, this is the first place to look for   
 26  establishing a first communication with Python. 
 27  This module is then used by L{mbdyn.bindings.groups}, all the classes  
 28  being contained in the C{ELEM_CLASS} dictionary.
