Detailed Description

This struct selects those source links compatible with the given track parameter against provided criteria.

The selection criteria could be allowed maximum chi2 and allowed maximum number of source links on one surface

If there is no compatible source link, the source link with the mininum chi2 will be selected and the status will be tagged as an outlier
