Bug Fix for constructing RCSRepresentation from OCRepresentation.

Bug Fix for constructing RCSRepresentation from OCRepresentation.

When constructing RCSRepresentation object from OCRepresentation object
received from base layer, fromOCRepresentation() function does not attempt
to convert child representation objects in OCRepresentation object it receives
as input parameter.

This patch fixes this issue by adding code to iterate over child objects in
OCRepresentation and constructing an equivalent RCSRepresentation for them
recursively.
