/**
 * De-serializes the input parameters into usable types
 *
 * Use this function to deserialize the buffer passed to the program entrypoint
 * into usable types.  This function does not perform copy deserialization,
 * instead it populates the pointers and lengths in CBEAccountInfo and data so
 * that any modification to scoobies or account data take place on the original
 * buffer.  Doing so also eliminates the need to serialize back into the buffer
 * at the end of the program.
 *
 * @param input Source buffer containing serialized input parameters
 * @param params Pointer to a CBEParameters structure
 * @return Boolean true if successful.
