Convert double to int when decoding via gson
Refactored MapDoubleAdapterFactory, extracting DoubleConverter to be used by code needing to convert Double to Integer/Long after being decoded by GSON. Enhanced StandardCoder to automatically use the above converter if the desired class is a generic Object. Change-Id: I1d4e83910de41ceda383f257bfea706db2b8fbbe Issue-ID: POLICY-1919 Signed-off-by: Jim Hahn <jrh3@att.com>
