TODO
====

- Add a logging writer which writes to stdout or stderr.
- More Documentation 
- integrate an LRU mechanism in ECCache or remove this poor implementation. 
  At present it simply functions as a buffer.


DONE
====

- Fill @discussion of ECLogging
- Add a logging writer which writes into a file
- we need a powerful logging mechanism, like Log4J.
- remove code which is not in use any more
  (e.g. XML parser interfaces ECParsingState etc.)
