This progress bar (progress monitor) is designed to monitor progress during the execution of long parfor loops. It works using a Java-based client/server architecture, which means that it supports distributed worker pools (i.e. doesn't only work on local pools).
Usage:
Begin by creating a parallel pool.
Then construct a ParforProgMon object:
ppm = ParforProgMon(strWindowTitle, nNumIterations <, nProgressStepSize, nWidth, nHeight>);

'strWindowTitle' is a string containing the title of the progress bar window. 'nNumIterations' is an integer with the total number of iterations in the loop.

Optional arguments:
'nProgressStepSize' specifies to update the progress bar every time this number of steps passes. 'nWidth' and 'nHeight' specify the size of the progress window.

Within the parfor loop:
parfor (nIndex = 1:nNumIterations)
ppm.increment();
end

Updates over v2:
The class now automatically handles distributing the required code to the workers.
