v0.4.0

Added

• Endpoint.TryGetCachedResult method, to retrieve a cached result synchronously for the given query argument.
• New IQuery and IQuery<TArg, TResult> interfaces, to help with testing or writing methods that operate on queries.
• Lots more tests (currently 96% line coverage in Phetch.Core).
• Lots of improvements to the sample projects (in samples).

Changed

• Public constructors for Query are now deprecated, because they serve very little value since adding Endpoints. Instead, just create an endpoint and call .Use(). These constructors will be removed in a future release.

Fixed

• Exceptions in OnSuccess/OnFailure callbacks are now caught, instead of being incorrectly treated as a query failure.
