28/04/2013: Better  reporting for file format problems, and bugfixes, for reading "force" files - previously obscure errors were generated when there was en empty line at the end of the file.
3/4/2013: Increased error checking.  In particular, errors are now generated when files have no rows, and correct warnings are given when C cannot be estimated correctly.
6/3/2013: Minor updates related to compilation problems.
25/09/2012: Increased the number of files that can be handled from an integer to a long, making this effectively infinite. Also replaced many other integers with longs to allow more than 2^16/2 individuals.
18/09/2012: Fixed a bug by which non-square chunkcount matrices sometimes (unpredictably) accessed invalid memory when calculating c.  This led to unpredictable crashes. Additionally, updated the warning message for non-square matrices.
OLDER: Numerous undocumented bugfixes.
