Client library for the Dropbox API

# Sets up an OAuth driver based on the current JavaScript environment.

# security issues. node.js application must always use authDriver.

# @private
# This method is called by {Dropbox.Client#authorize} when no OAuth driver is
# set. It should not be called directly.

# @throw Error if the current enviornment does not support auto-configuration
