_Scenario_

Standard cmsRun Process building interface used for data processing
for a particular data scenario.
A scenario is a macro-data-taking setting such as cosmic running,
beam halo running, or particular validation tests.

This class defines the interfaces used by the Tier 0 and Tier 1
processing to wrap calls to ConfigBuilder in order to retrieve all the
configurations for the various types of job
