In this commit:
* Bumped the draft revision to 0.5;
* Added view attributes to the proxy object attributes in place of the block pointer so that proxy object attributes would also report stride information;
* Added a clarification to the functionality section RE the potential overhead of synchronization and how it might be better to suffer that overhead in cases where direct access to the block memory would have more overhead in aggregate (e.g. with co-processors);
* Clarified the synchronization policy naming conventions.
