Refactoring of package-structure. Multiple sub-packages have been
externalized to own projects. Removed the naive approach for taking the
largest cell and updated log-messages to recommended log4j2 style
README update and included experimental classes
added .gitignore
Changed some log-messages to TRACE level instead of DEBUG and updated
code to latest state. Training the classifier and persisting the data
should now work - at least for Naive Bayes classifier. Some Issues with
SemiSupervised algorithm noticed as there is content retrieved after the
first iteration. Initial prediction (Supervised algorithm) seems to
work.
Added TrainingDataStorageMethod and Classifier selection to
configuration file and into Main and TextExtractor base class. Adapted
creation of naive Bayes classifier in all calling classes respectively
MINOR gitignore update due to switch  from Eclipse to IntelliJ
ADDED super-pom to simplify updating version numbers of dependencies
