add dox + grunt task.

housekeeping
expose parseActions as a method on Models & Collections
expose parseEntities as a method.

Will come back and use this later to disable/enable auto resolution of linked entities
Add autoFetch option

autoFetch can either be "all" or "linked"
add something useful to the readme
