ParseFrom equivalent for javacript protobuf files

[Karun Tahilramani]

I understand that protobuf compiler for javascript doesn't create a parseFrom method like it does for the java platform.  Appreciate some guidance on how to get an output from deserialized data similar to how parseFrom would work in java.  Otherwise, I can only see data as an array of Uint8 numbers.  When you output log to a development console, it's easier to make sense of the output if it's in a JSON format with actual string values, not a numeric representation of them.
