A handler for determining if the given execution context is user specific
or not. The token object returned by this handler is expected to uniquely
identify the current user if the context is user specific or to be
<code>null</code> if the context does not contain any resources or details
specific to the current user.

The user token will be used to ensure that user specific resources will not
be shared with or reused by other users.
