* graph.cc: added the option `-S -1' (i.e. symbol_number == -1)
which specifies that symbols are not to be drawn. This is a slight
change from the old convention, but is not consistent with the way
line_mode is handled, and both will behave better when `-K' or
`-M' are chosen respecively.

* graph.cc: the option `-m -1' (i.e. line_style == -1) means that
lines are not drawn between points. This allows you to plot
symbols alone at each point.

* graph.cc: added ability to specify the position of the labels
on the x and y axes using the letters R or L and T or B to indicate
whether the labels appear on the left or right and top or bottom
of the plot. Also added a description of this to graph.tex.
* graph.cc: added command line options to specify that the
line style (-L) or symbol (-K) changes whenever the abcissal
* graph.tex: added description of -K and -L options.

* graph.cc: replaced sprintf calls with dtoa, since sprintf
is apparently pretty broken on some systems.
* eGetOpt, ePlotFile: explicilty list constructrs, since g++
no longer allows inheritence of ctors.

* graph.cc: add margins beteen edges of the data and the box
only if the scale is not logarithmic. Otherwise the
additional margin could cause the value at the end of the

* The -c option was incompatible with other versions of graph.
Changed graph.cc to use this option to specify a default
label to be printed at each data point. Symbols can be
specified now using the `-S' option.
* Added the option `-z' to prevent graph from reading the standard
* split out read_data, tick_interval, eGetOpt, and ePlotFile
into separate files. Had to change the arguments to read_data
to include what used to be passed through global data.
* graph.cc: changed expressions using ?: to use >? or <? to
find the minimum of ints.

* If there is no data, we can still draw a frame around the
plot with axes and tick marks. Added if (point.length()=0)
around the code which searches for upper and lower bounds
on the data. Added it likewise before the code which plots

* Removed clipping of output coordinates and replaced it with
a warning. Now you can generate coordinates which may cause
plot to choke, but you will be warned.
* added ^L's and comments before each major part of the program.
C-x ] puts you at a comment for the next section of code.
* shortened inline functions for transformation of coordinates, px,
py, fx, and fy, to a single expression. Separated out clipping into
a new function, clip, which returns a value between 0 and PLOTSIZE.
* made usage and copyright notices constants.
* skip white space after reading y coordinate and label
so that the test for istream.good() will detect end of file
immediately and drop out of the read loop before trying
to read the next coordinate.
