Define the interfaces to create ReadWriteModifyRule operations.
Cloud Bigtable has operations to perform atomic updates to a row, such as incrementing an integer value or appending to a string value. The changes are represented by a ReadModifyWriteRule operations. One or much such operations can be sent in a single request. This class helps users create the operations through a more idiomatic C++ interface.
