Detailed Description
For support of multithreading.
The –tbs option directs ossimViewshedUtil to create a thread for each sector (using the SectorProcessorJob). Otherwise, the threads are mapped to a single radial. There are 8 sectors total (45 deg each) so a max of 8 threads are launched. Thus it may be faster to use the RadialProcessorJob scheme (default) when the number of available cores > 8.

Abstract method and must be overriden by the base class.
The base ossimJob will call run from the start method after setting some variables.
Implements ossimJob.
