Example for cross_validate fails

[joehuchette]

julia> (c, v, inds) = cross_validate(
        inds -> compute_center(data[:, inds]),          # training function
        (c, inds) -> compute_rmse(c, data[:, inds]),    # evaluation function
        n,              # total number of samples
        Kfold(n, 5),    # cross validation plan: 5-fold
        Reverse)        # smaller score indicates better model
ERROR: `cross_validate` has no method matching cross_validate(::Function, ::Function, ::Int64, ::Kfold, ::ReverseOrdering{ForwardOrdering})

Looks like the 5 argument version was removed at some point.
