Provide tagged string template functions

[VitorLuizC]

Would be nice to provide tagged string template functions.

Something like:

normalizeWhiteSpaces`
  Hi, ${student.name}!
  How are you doing?
`;
//=> "Hi, Vitor! How are you doing?"

Seems that wouldn't be hard to do with current normalize functions. But maybe they should be scoped in a different way.
