                                        PropertyFunctor

Creates a python based property function that can be added to the
global property list.  To use, subclass this class and override the
__call__ method.  Then create an instance and add it to the
registry.  The __call__ method should return a numeric value.

Example:

  class NumAtoms(Descriptors.PropertyFunctor):
    def __init__(self):
      Descriptors.PropertyFunctor.__init__(self, "NumAtoms", "1.0.0")
    def __call__(self, mol):
      return mol.GetNumAtoms()

  numAtoms = NumAtoms()
  rdMolDescriptors.Properties.RegisterProperty(numAtoms)

__init__( (object)arg1, (object)arg2, (str)arg3, (str)arg4) -> None :

    C++ signature :
        void __init__(_object*,_object*,std::string,std::string)

__call__( (PythonPropertyFunctor)arg1, (Mol)arg2) -> float :
    Compute the property for the specified molecule

    C++ signature :
        double __call__((anonymous namespace)::PythonPropertyFunctor {lvalue},RDKit::ROMol)
