* commit '52fd7a98556ee8739148e2007a8a04ed5907d691':
Changed the name of the reference pccor cal table to avoid conflicts with master and 6.7.6 branches

Pull request #1075: CAS-14194

* commit 'b1e3123ed19a5629ffb6176fb67b4137ca5731c5':
  Added a test for this use case
  Fringefit now excludes antennas with too few visibilities to be usefully solved for in a solution interval
  Plumbed the logger throught to the fringefit grid builder
  Tweaked fringefitter to remove antennas that have almost no data in a solution interval
  Changed the fringefit least-squares routine to use modified cholesky method for factoring matrix
  Added a handler for gsl errors to FringeJones.cc

Changed the fringefit least-squares routine to use modified cholesky method for factoring matrix
This works better with ill-conditioned matrices, they say, and in practice it averts an annoying crash on a test case.
