probit sampling fo and io seems ok (no autocorel sampling)

Major changes:
- Replace fastsamplexuv by samplexuv when sampling fo/io as fo changes
the size of the "Data" hence changes the diagonal of R.
- eliminate fo from the input as it actually corresponds to:
 fo(o-io)/fo (first fo is the times you count it and the second the
normalization

Nota: a positive change may be to normalize w before applying fo/io
      This should give more latitude for o (avoid problem of w
      under or above 0 change the kind of relationship for o)
      It should also allow to eliminate the "size of the data" pb
      with changing fo as the normalization could play in both
      sens (intuition).
