Another few small steps further to being able to run a native ECD/CSE
pipeline. In this commit we've removed the collection reader because the
CASs will now come from the Hoop side through the KV2CAS transformer
hoop. We're also using our own class loader to load classes directly
before executing. This allows us to run within the project space instead
of relying on external classpaths
Another small step further. This time we're successfully loading the
base phase class as the generic phase implementation. Now we can load
and execute our actual annotators and analysis engines
Small tweak to configuration files to make the process a bit more
overseeable for the first tests
