-/**
- * FileSystem
- *
- * A FileSystem takes an `options` object, which can specify a number of,
- * options.  All options are optional, and include:
- *
- * name: the name of the file system, defaults to "local"
- *
- * flags: one or more flags to use when creating/opening the file system.
- *        For example: "FORMAT" will cause the file system to be formatted.
- *        No explicit flags are set by default.
- *
- * provider: an explicit storage provider to use for the file
- *           system's database context provider.  A number of context
- *           providers are included (see /src/providers), and users
- *           can write one of their own and pass it in to be used.
- *           By default an IndexedDB provider is used.
- *
- * guid: a function for generating unique IDs for nodes in the filesystem.
- *       Use this to override the built-in UUID generation. (Used mainly for tests).
- *
- * callback: a callback function to be executed when the file system becomes
- *           ready for use. Depending on the context provider used, this might
- *           be right away, or could take some time. The callback should expect
- *           an `error` argument, which will be null if everything worked.  Also
- *           users should check the file system's `readyState` and `error`
- *           properties to make sure it is usable.
