foamMonitor has new options to select columns of data, plot the data on
x-axis and the independent variable on y-axis, and to display a single
graph without refreshing periodically. It also now terminates cleanly,
removing the gnuplot processes behind it.
New options:
-columns | -c <cols> display specfied columns, comma-separated, e.g. 2,4
-flip | -f plot data on x-axis, independent variable on y-axis
-once | -o print a graph one time without refreshing
These options add the ability to show the plot in the terminal, and at
any size. This is intended to facilitate monitoring on remote machines
where launching an X11 application may not be convenient or possible.

e.g. data files written by functionObjects
Attempts to interpret automatically the format of time-data files
Works successfully with majority of time-data output, e.g. forceCoeffs,
but will be unsuccesful on files with inconsistent output format
