Detailed Description

This handler encapsulates functionality which provides mechanisms for the SuperCore to perform API specific actions without there beingg "up-references" from the SuperCore to APIs. If these referencesg were allowed in the implementation, the cohesion would be too high and adding an API would be more difficult. The SuperCore is supposed to be largely independent of any API.
