Incorrect docs regarding creating text snippets

[spookylukey]

The README claims:

You can use any logic you like for the text snippets: constants, functions...

As far as I can see this is incorrect. The method relies on parsing Elm source code for a fixed set of constructs (concatenation etc.) in order to generate strings. Anything outside that will not work when it comes to the translated versions - doing something as simple as adding brackets to an expression makes it fail - and it's pretty unclear to me how it could ever be made to work with arbitrary functions.

Maybe this should be:

You can use Elm syntax for the text snippets (with a fixed set of constructs including concatenation)
