"Re-size windows to my preferred setup with an editing buffer at top left,
RE-Builder in a very short middle window, and R in a short bottom window.
This now uses a 'side-window' for R, effectively making it the only buffer
that can be displayed in the bottom window and sets 'window-size-fixed' for
RE-Builder.
The code for locking the size of RE-Builder is probably redundant
since it uses both options 'window-preserve-size' and 'window-size-fixed', but
it seems to work and that's what I'm interested in.
Note that the general goal here is to keep RE-Builder and R from being split,
so that only the top window is split to display help/man/R help buffers. Most
docs/forums recommend doing this w/ 'split-window-threshold', which doesn't work
here because the width of the 3 windows is the same.
As of 2019.05.25, now contains code for using R, python, shell,

"Function to quickly return the value of a calculation. The function searches
backwards for a \'j\' character to mark the beginning of an expression then makes
the region from the end of the line to the \'j\' the expression that is then
evaluated in calc and R. Evaluation in both programs provides a means of
double-checking the results, since both R and calc have their idiosyncracies."
