Haskell type information unification

:warning: WIP :warning: 
Say you have the declaration:
```objc
/// some comments
- (RACTuple *)divideWithAmount:(RACSignal 
  *)sliceAmountSignal fromEdge:(NSLayoutAttribute)edgeAttribute;
```

Yet you have [another library](https://github.com/maxpow4h/hrac) written in Haskell that has extra type information about that function.

With this, you can parse the Haskell file and add Haskell's type information about that function to the objective-c's docblock.

I.e.

```hs
p_hs <- runHaskellParser $ parseHS "Fixtures/RCL.hs"
p_rac <- runClangParser $ parse "Fixtures/test_header.h"
let c_rac = parseDocs TomDocParser p_rac
    c_rac' = p_hs ~> c_rac
```

will parse:
```hs
divideWithAmount_fromEdge :: TypeLC t
                     => Func (RACSignal CGRect)
                     -> Func (RACSignal CGRect)
                     -> NSLayout
                     -> Bind t TTrue (RACSignal CGSize)
                     -> OM (Bind Local TTrue (RACTuple (RACSignal CGSize) (RACSignal CGSize)))
```

and produce:


    # Description:
    ```
    Func (RACSignal (CGRect)) -> Func (RACSignal (CGRect)) -> NSLayout -> Bind (t) (TTrue) (RACSignal (CGSize))
    -> OM (Bind (Local) (TTrue) (RACTuple (RACSignal (CGSize)) (RACSignal (CGSize))))
    ```
    ) `-divideWithAmount:fromEdge:` (InstanceMethod [`id`]) [DecLeaf (Left (CommentParseException
    {file = Nothing, line = Nothing, message = "Comment not found"}))
    `sliceAmountSignal` (Parameter (Just `id`)),
    DecLeaf (Left (CommentParseException {file = Nothing, line = Nothing, message = "Comment not found"})) `edgeAttribute` (Parameter (Just `id`))
