changes slot beta of a CGHoptions object

.Object

an object of the CGHoptions class

CGHo["beta"] sets the proportion of each Kmax in multiKmax. If uniKmax[[i]] is the Kmax of profile i then

\code{multiKmax} = β \times ∑_i \code{uniKmax[[i]]}

MultiKmax must be greater than the number of profiles, but should not be too small since it should be greater than the selected number of segments (unknown).
