The basic matching algorithm is in this class while some specific column category matching and column building must be specified in derived classes. <p>A Recognizer is created per candidate aggregate table. The tables columns are then categorized. All errors and warnings are added to a MessageRecorder. <p>This class is less about defining a type and more about code sharing.<P><P><DL><DT><B>Version:</B></DT> <DD>$Id: //open/mondrian-release/3.0/src/main/mondrian/rolap/aggmatcher/Recognizer.java#2 $</DD><DT><B>Author:</B></DT> <DD>Richard M.
