had omitted to allow for a case where I had relaxed a tolerance slightly
- so a value of -1.0003 e -7 slipped through. This can happen so
I have just removed asserts - as I said they were originally in for debug
but I was being a bit stupid leaving them in as I was testing code on large
problems but by then NDEBUG was defined so asserts were turned off!</font>
