class AliITSUClusterLines: public TObject

This class is used by the AliITSUVertexer to compute and store
information about vertex candidates.
The cluster is seeded starting from two lines, then it is
possible to attach other lines. Whenever a new line is attached
the weight and coefficient matrices are computed.
