* Currently implemented selectors:
* - /User/id (similar to the classic {n}.User.id)
* - /User[2]/name (selects the name of the second User)
* - /User[id>2] (selects all Users with an id > 2)
* - /User[id>2][<5] (selects all Users with an id > 2 but < 5)
* - /Post/Comment[author_name=john]/../name (Selects the name of all Posts that have at least one Comment written by john)
* - /Posts[name] (Selects all Posts that have a 'name' key)
* - /Comment/.[1] (Selects the contents of the first comment)
* - /Comment/.[:last] (Selects the last comment)
* - /Comment/.[:first] (Selects the first comment)
* - /Comment[text=/cakephp/i] (Selects the all comments that have a text matching the regex /cakephp/i)
* - /Comment/@* (Selects the all key names of all comments)
*
* Other limitations:
* - Only absolute paths starting with a single '/' are supported right now
