* Find Records
*
* get /:modelIdentity
* * /:modelIdentity/find
*
* An API call to find and return model instances from the data adapter
* using the specified criteria. If an id was specified, just the instance
* with that unique id will be returned.
*
* Optional:
* @param {Object} where - the find criteria (passed directly to the ORM)
* @param {Integer} limit - the maximum number of records to send back (useful for pagination)
* @param {Integer} skip - the number of records to skip (useful for pagination)
* @param {String} sort - the order of returned records, e.g. `name ASC` or `age DESC`
* @param {String} callback - default jsonp callback param (i.e. the name of the js function returned)
