Adds support to pass multiple values when creating many objects

This pull request tries to fix #81 issue based on the `Sequence` concept as it was first imagined in #100. This is just my initial idea and if @vandersonmota is OK with it, the next two steps would be:

  * To create a custom exception to handle with possible `IndexError`;
  * To move `Sequence` and `UnpackingSequence` from `recipe.py` into a `sequences.py` for the sake of semantics;
