# Build on a class that has been created in C
# C defines the following:
# Configure_Dump - Return a dict of the current state
# Configure_Get  - Return a single value from the current state
# Configure_Set  - Set a new value for the current state
# Configure_Delta - Return a list of all of the values that have a script
#                   binding and were modified since the last call to Configure_Delta
