Introduction

This package contains virtual interfaces for tools to be used for track-based alignment.

Class Overview

The package contains the following classes:

• IAlignTrackPreProcessor: processes the collection of Tracks and creates a vector of AlignTracks
• IAlignTrackCreator: processes AlignTrack and assigns a collection AlignTSOS to it
  
• IAlignTrackDresser: dresses AlignTrack with derivatives, residuals, etc.
• IAlignTool: accumulates information from tracks and solves for alignment parameters
• IAlignModuleTool: provides methods to handle AlignModules and AlignPars
• IFillNtupleTool: can be inherited by detector-specific tool to write output ntuple
  
• IGeometryManagerTool: inherited by detector-specific tool for building geometry of AlignModules to be aligned
  
• IMatrixTool: inherited by MatrixTool and IPCMatrixTool for dealing with large matrices
• IDerivCalcTool: inherited by tools that calculate derivatives
• IJacobianManagerTool: not yet used
• ITrkAlignDBTool: used to read constants from the database and write constants (to ASCII file for now)
