Implemented FeedODataFacade.GetLatestVersion method.
Added a public constructor to (CPV) Version to allow constucting version instances from a given version string.
Extended Version class with new method, Next(), that increase a version by one and returns a new (immutable) reference to it.
Refactoring of the Version class. Mainly introducing the 'sequence' lingo for the auto-increasing number used by CPV versions and the corresponding algorithm.
Implemented an overloaded Version.Next(string) that accepts a 'last' version to be given and knows how to base the next version on either that, or (if the static part of the two deviate), starts a new sequence.
