Multicore - Parallel processing on multiple cores

Performance improvement especially for projects using many slave processes.

Added parfor-loop to demo.

Performance improvement - especially when using a large number of slaves

New features:
1. Slave settings can be set via command line argument.
2. Slave Matlab process can be quit after a given time in seconds.

Bugfix: calling startmulticoremaster.m without settings works now.

Typo fixed.

Typo fixed.

Overhead resulting from expanding the function handle cell reduced.

Description changed again.

Links in help lines corrected.

Description modified to make it more concise.

Only E-mail changed in html document.

Bugfix.

Small changes to documentation and gethostname.m

Structure being passed to post-processing function changed (still undocumented feature)

Estimation of time left changed, post-processing function introduced.

Bug fixed.

File displayerrorstruct.m was missing.

Call to "clear functions" now in master and slaves, bug fixed.

In each multicore run, "clear functions" is now called once to ensure that changes to m-files take effect.

Two bugs fixed, one regarding the waitbar, one regarding the semaphore mechanism.

Using system-dependent file separators in paths again. Waitbar shows progress during parameter file generation now.

Added estimation of time left in waitbar.

Added an optional waitbar.

If a slave is killed during working on a job, the master will now generate the parameter file of that job again instead of working on the file himself. This will increase performance in certain situations.

File regexptokens.m added.
Dicussion group created: http://groups.yahoo.com/group/multicore_for_matlab

Another change to the semaphore mechanism.

I have nearly re-written both master and slave in order to make the package even more robust and to reduce the overhead for inter-process communication.

Introduced parameter EVALSATONCE which causes the multicore package to do several function evaluations after each other before saving/loading and thus reducing the communication overhead. Demo function MULTICOREDEMO heavily commented.

Semaphore mechanism improved.

Forgot to include file chompsep.m

Semaphore stuff improved.

Subfunction datenum2 was not needed.

A subfunction that is only executed on certain systems was missing.
