SPK::Interpolator + loopingEnabled bug

in SPK_Interpolator.cpp, line 74-91 and possibly below
You use end() as pointer to last item in the container.
end() is an invalid iterator pointing BEYOND end of the container, you must not attempt to dereference it, change to rbegin() or back() instead.

oops, you re right. That s a beginner's mistake. Must have been tired that day. I ll fix that this evening.
Thanks for reporting

Fixed on the svn (revision 142)
