New in 0.5.1:

• zvres lcio.h build fix, zvres part of build
• BeamSpotSingleton turn the warning msg into an info msg
• skeleton code added for vertex reconstructor
• warns now if you try to configure with value(param-value), instead of value:(param-value).
• doesnt allow self-nesting mvf anymore
• fixed memory management bug

Open issue:

• Why is zvres performance so poor?
