Implement methods to analyse:

Implementation of interface analysis: https://github.com/tendermint/starport/blob/88781ee/starport/pkg/cosmosanalysis/module/message.go#L22-L61

Implementation of types: https://github.com/tendermint/starport/blob/8863e892686bdff28ece8cf0c88db43a93764a4e/starport/services/scaffolder/component.go#L196-L232

Hey, is this up for grabs? Would love have a shot at this.

@bensooraj I don't see why not! 🙂 Since this is a non-trivial issue (from my perspective), I think the best way to approach this is to make a small PR and incrementally push code to it, so we can all be in sync about how it's implemented.

@fadeev Perfect! On it!
