/**
* @class ElggFile
* This class represents a physical file.
+ *
+ * Usage:
+ * Create a new ElggFile object and specify a filename, and optionally a FileStore (if one isn't specified
+ * then the default is assumed.
+ *
+ * Open the file using the appropriate mode, and you will be able to read and write to the file.
+ *
+ * Optionally, you can also call the file's save() method, this will turn the file into an entity in the
+ * system and permit you to do things like attach tags to the file etc. This is not done automatically since
+ * there are many occasions where you may want access to file data on datastores using the ElggFile interface
+ * but do not want to create an Entity reference to it in the system (temporary files for example).
+ *
