* Adds the basic structure for required to add grpc support Added the message implementation Updated the code to confirm to the protocol flatbuffersobject Adds an example for Swift flatbuffers GRPC Started implementing the swift GRPC code Gen Generator generates protocols now Fixing ci issues Migrated the logic to use grpc_generator::File instead of string Refactored swift project Implemented GRPC in swift Finished implementing GRPC in swift Fixes issues Adds contiguousBytes initializer to swift Adds documentation + fixes buffer nameing in tables + structs Adds documentation + fixes buffer nameing in tables + structs Updated tests * Updated version
