Merge pull request #22 from tpjg/model-links

Implemented Model.Reload
Error in GetSiblings prevented Links from populating
Bugfix - was not setting Vclock when storing objects, possibly resulting in lots of siblings

This commit fixes the problem, a test still needs to be written; also a test for the "Links" (previous) commit still needs to be written.
