Revamp

Trying to cleanup the codebase to support #75. Old tests passes. Plus one new test case for #75 passing...

A few things missing:

• Path deviation
• Perhaps something is missing in routeMethod, see code that are commented out

Now I need to rest for a few days.

Since args/params/paths are tightly correlated we can't really split them completely.

So I decided to parse each route in the following order:

1. parse @:params into Parameters, with some prelim test against the raw arg list
2. parse @:<method> into Paths, with some prelim test against the raw arg list (but not yet implemented)
3. Use params and paths to create Arguments, which is a "rich" arg list containing all useful information.

I didn't (can't?) port the path deviation object because I am not sure what it is doing. @back2dos can you add a few test cases to illustrate it?

I removed the toCamelCase transform (which is a breaking change) because we can now specify the exact header name by @:params(foo = header['x-tink-web'])

and

function get(headers:{
  @:name('x-bar') var bar:String;
});
