class_docstr: A PClass is a python class with a fixed set of specified fields. PClasses are declared as python classes inheriting
  from PClass. It is defined the same way that PRecords are and behaves like a PRecord in all aspects except that it
  is not a PMap and hence not a collection but rather a plain Python object.
  
  
  More documentation and examples of PClass usage is available at https://github.com/tobgu/pyrsistent
