Implemented the method of storing every operation done to each document  instead of the documents explicitely.  The tests which do not pass are labelled NOT IMPLEMENTED due to current limitations on the ability to query sub-attributes of documents.

Revised bryanstorage so that a log of puts and removes is recorded.  All tests involving getting, putting, removing, and querying from other storages are passing.  Currently, the allDocs method is not implemented correctly, but there are several placeholder tests written which demonstrate the desired functionality.

Tests are not passing, but no longer having error with options passed to QueryStorage.buildQuery as undefined.

bryanstorage now uses querystorage and uuidstorage as substorages to implement uuid posting and querying the sub storage.

Updated bryanstorage to retain all versions of documents and only retrieve the most recent copy when get(id) is called.

Added _ parameter to metadata of bryanstorage documents, which increments each time put, putAttachment, or removeAttachment is called on the document.  Created tests to test these features.

Added src/jio.storage/bryanstorage.js and test/jio.storage/bryanstorage.tests.js for revision storage implementation.
