<p>Runs one unit of work, making the root Objectify context available. This does not start a transaction,
but it makes the static ofy() method return an appropriate object.</p>

<p>Normally you do not need to use this method. When servicing a normal request, the ObjectifyFilter
will run this for you. This method is useful for using Objectify outside of a normal request -
using the remote api, for example.</p>

<p>Alternatively, you can use the begin() method and close the session manually.</p>

@return the result of the work.
