The uimaj-ep-runtime plugin depends on EMF, this dependency makes deploying in
an non eclipse OSGI environment difficult since EMF depends on org.eclipse.core.runtime,
which depends on many other eclipse plugins.
Since EMF is only really used in the examples project, the dependency is removed
from uimaj-core and the classes Ecore2UimaTypeSystem and UimaTypeSystem2Ecore.java
are moved to uimaj-examples.
The uimaj-ep-runtime plugin contains currently uimaj-examples, that
could be moved to a seperate plugin or shipped with an OSGI bundle.
