Add methods

[gkpty]

methods or transformations are applied at three different levels:

1. component: Component methods are executed within the component loop for each component before the component is replaced.
2. object: Object methods are executed inside the object loop before an object instance is added.
3. template: template methods are executed for each template (file) after the toruf compiler (after all components and objects have been replaced).

methods are stored in the methods directory were they will be inside a dir according to their level of execution.

methods are javascript files that have several built in methods to help you write your transformations faster.
