Detailed Description

A Generic Algorithm info management class. SiPixelGenError contains thePixelTemp (a std::vector of SiPixelGenErrorStore, each of which is a collection of many SiPixelGenErrorEntries). Each SiPixelGenErrorStore corresponds to a given detector condition, and is valid for a range of runs. We allow more than one Store since the may change over time.

This class reads templates from files via pushfile() method.

The main functionality of SiPixelGenError is qbin(), which produces algorithm info on the fly, given a specific track's alpha and beta.
