/**
* \brief Merge two CastleProto prototypes together, if possible.
* \brief Merge two CastleProto prototypes together, if possible. If a
* particular repeat from c2 is already in c1, then it will be reused rather
* than adding a duplicate repeat.
*
* Returns true if merge of all repeats in c2 into c1 succeeds, and fills
* mapping with the repeat indices.
