[#1] Add first protocol buffers message and print its serialization to terminal

@TejasSC I've looked into your error. Unfortunately, I see the same build error 😞
There's this open issue on Github:

• Compile failure with proto-lens-combinators-0.1.0.8 google/proto-lens#110

Try for now to build with stack instead. Maybe this can resolve your issue.

@TejasSC Does it work if you only do something simple with ghcid? Like, printing string Hello, world! into terminal? Without imports and other stuff.

[chshersh]

@TejasSC I've created issue #4. But let's do #4 in separate PR. I will consider this PR done when you're able to print encoded message using ghcid. I see that this is already implemented. Could you paste output in comment here?

Following is after "Registering library for proto-route-0.0.0.." line

GHCi, version 8.2.2: http://www.haskell.org/ghc/ :? for help
[1 of 1] Compiling ProtoExports ( src/ProtoExports.hs, interpreted )

This is really great that current results are possible! Some refactoring is required. But I guess we're moving in the right direction.

I think it's actually useful to keep previous content of changelog file.

[chshersh]

I see that LICENSE is changed. Could you please return back to previous license?

[chshersh]

The previous content of README file also can be returned back

[chshersh]

Maybe you could try to use latest resolver from Stackage? I guess we figured out that the problem was not in LTS. So I think you can use newer GHC version. And also you can remove those packages from extra-deps that are in the LTS resolver you're going to use.

Okay, let's actually move this chunk of code into library stanza. So Main.hs file will look like this:

import qualified ProtoRoute

main :: IO ()
main = ProtoRoute.main

This will make executable stanza very small (almost no dependencies). And we will put all logic into library. This is better for further modularity.

[...][1] or [...][2] should point to some links. But links are missing in this file.

[chshersh]

@TejasSC Could you also write lines like

Resolves #1
Resolves #2

in the body of your PR? This will close issues automatically when PR is merged.

Unfortunately, this won't work 😞 The initial content of proto-route is the following:
