 * Get File By Id

 * Retrieve a list of documents in the user's library. Optionally specify a

filter to find only files with matching labels or paths. This method

returns only metadata about files; to download a file, call

`GET .../files/{file_id}/download`

When specifying qualifiers with your request, only files that match

_all_ qualifiers will be returns. So, for example, if you specify

`label='financial'` and `status='UPLOADED'`, only files with the label

"financial" AND status UPLOADED will be returned.
