Tool to generate functions.go based on rules descriptor

[rameshpolishetti]

Current behavior:
User has to write down functions.go with condition evaluators and action functions as defined in the rules descriptor json.

Expected behavior:
Add a cli tool or flogo cli plugin to generate functions.go boilerplate code based on supplied rules descriptor json.

What is the motivation / use case for changing the behavior?

• Improves turn around time to create and run a new rule application.
• Eliminates human errors caused due to mismatch function names (usually spelling mistakes) between descriptor json and functions.go

Additional information you deem important (e.g. I need this tomorrow):

Hmmm - I guess? Honestly I'd prefer this to be done:

1. Conditions utilize the flogo expression language with bindings to the Tuple store
2. Action functions - same thing (or wrap it in an activity if used within a flogo flow)

Doing a code generator isn't really moving the needle.

I think all this is asking is for stubs to be generated and save some typing/and errors. (unlike the elaborate codegen in BE) So it would be a good little nifty utility to have.. "(2) that Matt mentioned above would be really cool.. When a rule fires, execute a Flogo-flow.. That would be a nice ER. And of course (1) above, which was done but broke when Flogo-core changed their APIs. That needs to be redone.

I echo @balamg, points 1 & 2 mentioned by @tibmatt are really cool !!
Not sure about the complexity involved in point 1 & 2 realization, until then this kind of tool saves some time/errors.

Closing this issue as this kind of tool may not be required as issues #22 & #69 effectively handles the problem statement.
