Replaced local MetaGenerator with MetaServer and put MetaGenerator in
a remote, stand-alone class
MetaGenerator is now a stand-alone, remote metadata server but
can still be used to locally read dataless if desired.
Minor change to MetaServer
Small change to MetaServer request output
.. still toying with MetaGenerator/MetaServer output messages ...
Fix to MetaGenerator/Server output
Fixed minor null pointer error in AvailabilityMetric when availability > 100%
Merge branch 'master' into develop
Replaced java.util.logging with org.apache.log4j in ALL classes.
Because of this, all the cfg:log stuff could be moved out of config.xml
and into (a much more streamlined) log4j.properties.
Put samples directory back in
