rudimentary tick positions

[Shai Ayal]

attached is a patch for rudimentary tick position calculations. It is
a translation of Tom Holroyd's python code which he posted to this
list some weeks ago (Tom, I hope that by posting the code here you
agreed to it's use in octave ...).
What is missing is:
*) log axes ticks
*) minor ticks
*) does not take into account the axes size and font size to eliminate
tick overruns
*) gnuplot interaction
*) your favorite feature here

Still, I think it is good enough to serve as a basis to the above improvements.
