/**
 * Why?
 * Because some of the field names in a model may conflict with those from Sugar class. 
 * Simply adding a serialize command to those fields will throw exception listed below.
 * 
 * So, we add serializedName to all fields in such models and decode only those with 
 * serializedName using this Gson exclusion strategy.

 * Exception: http://stackoverflow.com/questions/19315431/gson-tostring-gives-error-illegalargumentexception-multiple-json-fields-name
