Internal soundgen function.

1 2	interpolate(pitchCands, pitchCert, pitchCenterGravity, interpolWin = 3, interpolTol = 0.3, interpolCert = 0.3)

`pitchCands`	a matrix of multiple pitch candidates per fft frame. Each column is one fft frame, each row is one candidate.
`pitchCert`	a matrix of the same dimensionality as pitchCands specifying our certainty in pitch candidates
`pitchCenterGravity`	numeric vector giving the mean of all pitch candidates per fft frame weighted by our certainty in each of these candidates
`interpolWin`	when interpolating pitch candidates, the median is calculated over `<c2><b1> interpolWin`
`interpolTol`	when interpolating pitch candidates, the criterion for needing to interpolate is the absense of pitch candidates with values within `1 <c2><b1> interpolTol` of the median of pitch center of gravity over the interpolation window. For ex., if `interpolTol` is .05, we look for values from 0.95 to 1.05 time the median value over interpolation window.
`interpolCert`	when interpolating pitch candidates, all generated pitch candidates are assigned a certainty equal to `interpolCert`

Interpolation: if a frame has no pitch candidate at all (NA) or no candidate between the most likely candidates for the adjacent frames, add such a candidate with some (low) certainty.

Returns a modified pitchCands matrix.
