marked m-code 2 png (for latex formulas)

[Fotios]

The attached functions generate png formulas from a file with lines 
marked as

#f# $ <formula> $ <\n>

More precisely genmarked is a utility that returns a cell array of 
strings with the parts of interest, that is

$<formula>$

in the case of genpng; it accepts a marker as argument, thus can be used 
(does Octave have sth similar?) to "parse" files marked with whatever 
marker in an m-file (or any other simple text file).

You call like

octave:1> genpng ("example")

Any feedback? Tested on Windows 7, does it work on linux/Mac OS X? (it 
should!) I started doing that having in mind the publish function i 
wrote previously; to improve the html generation.

Enjoy
