EV/libev with Inline::C in perl

Can't comment on the quality of Inline::C, but it seems like a nice
little stepping stone to getting started with using C with perl (or at
least in my case it lets me focus on figuring out the C and not worry
as much about the XS stuff right now).

Right now, this is just an experiment to see how big of a benefit
re-writing in C will give. Inline::C seemed like a quick way to get
started and prototype. If fruitful, full fledge XS will be in order.

Thanks for the input, setting the following Inline::C options I was
able to get it working:

use Inline C => Config => INC => "-I/pathcontaingingEVandheaders/",
MYEXTLIB => '/pathto/auto/EV/EV.so',
AUTO_INCLUDE => '#include "EV/EVAPI.h"',
BOOT => 'I_EV_API("Inline");';

Might be worth adding as a note in the documentation (for those new to
C and XS such as myself)?

Thanks again for all the help!
