Python: Add Checksum to Graph Elements

Idea created by dave.lajoie_Presagis on Aug 15, 2017

    The concept of a checksum is based on object's property and would be returned as string, is same way python does it with hash(object) or class.__hash__()


    for instance:

    - its attributes ( key - pair )

    - its geometry


    where OID value would not be considered, since the OID value is always unique.


    This would allow to compare two graph elements in two graph layers, for example


    if ce.computeChecksum( graphNodeFromLayer1 ) == \
       ce.computeChecksum( graphNodeFromLayer2 ):
        print 'Yikes'
