mandel.py

Calls mandel.c to create an array of numbers generated 
using the Mandelbrot formula. Attempts to compile mandel.c 
if mandel isn't found on PATH. Writes an 8-bit binary file which
can be viewed in NIH Image or Photoshop, for example.

c		comma-delimited list of complex plane 
		delimiters: rmin,rmax,imin,imax
w		width of grid
n		number of cycles
v 		verbosity
nc		new coordinates - give pixel coords corresponding to some
		area within the plot of width w, bounded by coordinates c;
		will return new values for c. 
		new coordinates 
out		name of outfile

NOTE: To import into NIH Image, choose File --> Import
and select Custom, 8-bit, and set to appropriate grid width.

Rotate -90 degrees to maintain proper orientation!
