* @brief CTA observation simulator tool interface defintion
*
* This class simulates CTA observation(s) using Monte Carlo sampling of the
* source and background models. The class supports simulation of data of
* multiple CTA observations in one shot. If multiple CTA observations are
* processed and the save method is called, events FITS files will be written
* for each observation.
