Setter Method for the noOfSites slot in a parameterOptions object.

1	noOfSites(object) <- value

`object`	`object` is a `parameterOptions` object.
`value`	`value` is a positive integer that will be assigned to the `noOfSites` slot.

While computing Position Weight Matricies (PWM) from Position Frequency Matricies (PFM), it is possible to restrict the number of sites that will be used to compute the PWM. The default is set at "all". In this case, all sites will be used to compute the PWM.

Returns a parameterOptions object with an updated value for the noOfSites slot.
