NOTES.md

Everything is mostly based on helper:

• The {{> partial foo bar name=blabla }} is nothing more that helper that call the partial with that parameters
• The {{ foo }} it is an alias for {{lookup . "foo"}} also {{helper a}} it is an alias for {{ helper (lookup . "a") }}
• The {{#block a b c}} is the same as an helper, where the body of the block (the list of children) is passed as a parameter. And also the list of else

Also the function can return any type of value, so the {{}} or {{{}}} should apply a render function so {{ foo }} should be see like: render(lookup(".", "foo"))
