/**
* Loads entities and records from file-based structure
*
* Trys to implement a similar method to load datasets not from database, but rather from
* a file that holds all relevant model data and is laid into the filesystem of each library.
* This allows for easy default-data to be loaded without using a database as backend.
*
* Put your files into `{:library}\data\{:class}\{:name}.neon` and let the content be found
* with loading just the id or slug of that file.
*
* Attention: This feature is considered experimental and should be used with care. It might
* not work as expected. Also, not all features are implemented.
*
* If nothing is found, it just returns null or an empty array to ensure a falsey value.
*
* @param string|array $model fully namespaced model class, e.g. `radium\models\Contents`
* can also be an array, in which case `key` and `source` must be given
* according to the internal structure of `Model::meta()`.
* @param string $type The find type, which is looked up in `Model::$_finders`. By default it
* accepts `all`, `first`, `list` and `count`. Later two are not implement, yet.
* @param array $options Options for the query. By default, accepts:
* - `conditions`: The conditional query elements, e.g.
* `'conditions' => array('published' => true)`
* - `fields`: The fields that should be retrieved. When set to `null`, defaults to
* all fields.
* - `order`: The order in which the data will be returned, e.g. `'order' => 'ASC'`.
* - `limit`: The maximum number of records to return.
* - `page`: For pagination of data.
* @return mixed returns null or an empty array if nothing is found
* If `$type` is `first` returns null or the correct entity with given data
* If `$type` is `all` returns null or a DocumentSet object with loaded entities
