>       MULTI_REG object - for regression across multiple outputs

>        A=MULTI_REG(C,H) returns an multi_reg object which uses C as a
>        base classifier for each output, and is initialized with hyperparameters H.

>        Hyperparameters, and their defaults
>         child=C              -- the base classifier for each output

>        Model
>         [stored in children]

>        Methods:
>         train, test

>        Example:
>          a=multi_reg(svr('C=10'));
>          d=toyreg('n=10;o=5;');
>          [r a]=train(a,d)
