Changes in version 0.6 (2014-09-10)

Improvements:
- optimizations in the beam search algorithm
- significant memory optimization (dataset storage, access)
- ARFF: enable import of "empty" attributes, i.e., with an empty value domain (this can occur, for example, when importing columns with only 'NA' in R)
Bug fixes:
- exclude target from subgroup attributes
- fix loading of ARFF file, for attributes/values with trailing spaces
