Sampling wavelet Ridge
.DN
Given a ridge phi (for the wavelet transform), returns a 
(appropriately) subsampled version with a given subsampling rate.
.CS
wRidgeSampling(phi, compr, nvoice)
.RA
.AG phi
ridge (1D array).
.AG compr
subsampling rate for the ridge.
.AG nvoice
number of voices per octave.
.RT
Returns a list containing the discrete values of the ridge.

node:time coordinates of the ridge samples.

phinode:scale coordinates of the ridge samples.

nbnode:number of nodes of the ridge samples.
.SE
.DT
To account for the variable sizes of wavelets, the sampling
rate of a wavelet ridge is not uniform, and is proportional
to the scale.
