Wrong handling of ridge values<-1 in inversPeaksAndValleys

if (a - 0.6666667 < -1.5) {

'a' between -0.6666667 and 0. So a - 0.6666667 will be between -1.3333337 and -0.6666667.

You are absolutely right. I think this line should read

  if (a + 0.666667 < 0)

and the if above shouldn't have the ridge < -1 case.

I don't think the case with ridge < -1 is used anyways, but it makes sense to have this function correct in all cases anyways. I'll fix it eventually.
