Forecast conditional variances from conditional variance models

`V = forecast(Mdl,numPeriods)`

`V = forecast(Mdl,numPeriods,Name,Value)`

generates forecasts with additional options specified by one or more
`V`

= forecast(`Mdl`

,`numPeriods`

,`Name,Value`

)`Name,Value`

pair arguments. For example, you can specify
presample responses or conditional variances.
