Type to represent valid UNIX or Perl signals

MooseXTypesSignal exports a type, Signal, that recognizes valid signals on your platform. The underlying type is a non-negative number, but there is a coercion from strings to numbers that recognizes signals by name.

There are also more restrictive types, PerlSignal and UnixSignal. UnixSignal only understands signals that are in your system’s signal.h header file. PerlSignal only understands signals that are in Perl’s Config hash. Signal is either/or, with preference to UnixSignal over PerlSignal when coercing.
