Add old code for FFT filter/convolve
RangeExtender cannot override Range, because it cannot provide all of the collection functions without the "length" value!
... so we have to implicitly convert RangeExtender to Range at the "CanSlice[DenseVector[V], Range, DenseVector[V]]" stage.
Incidentally found that abs() is missing Int/Long implementation
Passing tests for DenseVector
DenseMatrix tests passing
