Inplane Functionality Release

This is the release of the new Inplane loading functionality. This release includes a migration tool (mrInit_sessionMigration) and a complementary unit test suite (to be released at the same time through a merge of a similar pull request on the Vistatest repository). As well, for testing purposes, a complementary vistadata release has been created which will need to be pulled from the svn repository.

I will leave this pull request open during the break for everyone to take a look at. I hope to complete this release upon my return if there are no issues. Please feel free to make any comments or ask any questions about this major update.
