/**
* 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.
