* Improved documenation for BoxyRatio
Modifed Eclipse .classpath so that the ontometrics project now finds classes in plugins-axiomatic.
Added a metric to calculate the proportion of asserted tbox axioms that we can represent using nice diagrams.
Using SPARQL with many filters seems to be a good way to go.
Pulled the Diagram related metrics into a separate plugin and factored out Karl's singletons into ontometrics-core
  - created a new toplevel maven project that builds all modules.
Fixed plugins-axiomatic metrics that needed to point at the previously moved Singletons now in ontometrics-core
  - Tarted up the description and metric abbreviation in AtomSubsetAtom to reflect its new calling in life.
Ensured that all modules compile and package without errors
  - ontometrics-core now depends on jena, so there's no need for modules to do so.
Don't use shipped Eclipst configuration, tell Eclipse to build it from Maven.
Struggling to get maven to run the top-level project.
  - Made plugin builds depend on ontometrics-core
Stupidly had incorrect package name for class
Factored SimpleQuery out into a separate class.
Added top-level project description.
Factored out more funtionality into SimpleQuery
Turned ontometrics-core into an Uber-jar just to make life running it easier.
Added second diagrammatic metric.
Alternative method of "bootstrapping" diagram metrics from SPARQL queries.
Added a default configuration for log4j
Added new diagrammetrics
More metrics for diagrams.
Disable loading of imported ontologies in Jena.
  - This is a major change.
