# HISTORY
# 2014-03-25
# o Added argument 'grid' to drawC1C2Density().
# 2012-04-16
# o CLEANUP: drawC1C2Density() for PairedPSCBS no longer needs to require
# 'aroma.core', because draw() for 'density objects are in R.utils 1.10.0.
# 2012-02-27
# o BUG FIX: drawC1C2Density() for PairedPSCBS would throw an exception
# if there was only one segment, or less than two finite (C1,C2):s.
# 2012-02-23
# o Moved drawC1C2Density() and plotC1C2Grid() to its own source file.
# 2011-11-12 [HB]
# o Added drawC1C2Density() adopted from plotC1C2Grid().
# o Now argument '...' of plotC1C2Grid() for PairedPSCBS are passed
# to plotC1C2().
# 2011-07-10 [HB]
# o Updated code to work with the new column names in PSCBS v0.11.0.
# 2010-10-08 [HB]
# o Added plotC1C2Grid() for PairedPSCBS.
# o Created.
