HiPi Interrupt Support

[Mark Dootson]

In response to Bill's prompting I have released a version of HiPi Perl modules with interrupt support implemented.

Full details and example scripts at http://raspberry.znix.com/2013/04/hipi-perl-modules-and-interrupts.html

It seems to work for me but obviously feedback and contribution from users would be a great help in improving the modules.

Regards

Mark
