// AlgTool to select high quality tracks for the inner detector 
// (Pixel+SCT) alignment algorithms.
// This AlgTool provides a track selection based on the following cut variables:
// Momentum, pt, number of shared hits, number of holes and chi2 probability. 
// Returns 0 in case a track is not accepted, otherwise 1
