Moved file KTTypeIndexFactory.hh to KTTIFactory.hh.
KTFrequencySpectrumDataFFTW and KTTimeSeriesData now have type-indexed KTDataMap factory registrars.
Bugs fixed and PS production tested (incl. attaching data to an event, and retrieving it by type & name).
Finished putting data map registrars in data source files.
Moved inclusion of KTDataMap from KTData.hh (previously there for convenience) to data-class source files.
