statusdots

 function statusdots(p,total,num)
 
 <p> is the index (starting from 1)
 <total> is the total number of things to process
 <num> (optional) is the desired number of dots.  default: 20.

 depending on the value of <p>, fprintf out an '.'
 such that we write out a total of <num> dots,
 equally spaced as best as possible.  we start
 with a dot when <p> is 1.

 example:
 fprintf('starting');
 for p=1:57
   statusdots(p,57,10);
   pause(.1);
 end
 fprintf('done.\n');
