A phase-space diagram is plotted for a one-dimensional map
according to the specified options. If the option for -dx
is non-zero, then two trajectories are plotted: one star-
ing at x0, and the other starting at (x0 + dx). See the
MAPS section of the manual page for details of what maps
are supported. User defined maps can be added to the file
maps1d.c, but you must recompile the program.

How to plot points.
The following four one-dimensional maps are allowed:
x(t+1) = 4 * r * x(t) * (1.0 - x(t))
x(t+1) = (x(t) <= 0.5) ? 2 * r * x(t) : 2r * (1.0 -
x(t+1) = sin(x(t) * PI * aux * 2 * r) / 2 + 0.5
x(t+1) = r * exp(-aux * (x(t) - 0.5) * (x(t) -

No sanity checks are performed to make sure that any of
the options make sense.
