This patch fixes the missing strict behavior during import.  It does this by
looking at the input values and quickly checking to see that all the keys in
the input are present in the model.  Anything that is in the input, but not the
model, causes an error.

Further, the import function now has knowledge of serializables, so that keys
found in the input that are the result of the serializable decorator, will just
be ignored, since they are synthesized, but valid members of the structure.
