A weighting sky map has been added to the CTA event cube that allows to correctly take into account data space selections. This is in particular needed for stacking event lists with different energy thresholds in an event cube, but can also be used for combining event lists with different ROIs.

…ground::elogmeans() methods

The exposure cube is now defined for energy values and not energy ranges.

…, but at least now a maximum likelihood fit works.

- table(std::string)
- has_axis(std::string)
- has_table(std::string)

The following methods have been renamed:
- GCTAResponseTable::tables(), was formerly GCTAResponseTable::size()
- GCTAResponseTable::axis_bins(), was formerly GCTAResponseTable::axis()

The following methods have been added to the public interface:
- GCTAResponseTable::axis(std::string)

It is still convenient to control the event disposal from the observation class, although the actual event disposal is now handled by the event list class.

…t GCTAEventList level.

If an event list is loaded the actual events are not read in, but only loaded upon request. This allows to save memory.

…ntList::append() method.
