changeGroupType - adds, removes, or toggles group types

### USAGE

        changeGroupType <group-list> [<group-type> | +<group-type> |
            -<group-type>]*

### DESCRIPTION

This command is used to selectively activate and deactivate types for a group or a list of groups.

If a type is preceded by a "`+`", the type will be appended to the list of types of the same class. For example, a newly added output function will follow any current output functions.

If a type is preceded by a "`-`", it will simply be deactivated. A type preceded by nothing will be toggled: if already present, it will be removed; if not present, it will be added.

This command returns a list of the new group types of the last group specified.

### EXAMPLES

To add noise to the output of the groups "out1" and "out2", remove their unit cost functions and toggle their `STANDARD_CRIT` criterion functions:

        lens> changeGroupType "out1 out2" +OUT_NOISE -COSINE_COST STANDARD_CRIT
        Input Type
          DISTANCE
        Output Type
          LINEAR
          OUT_NOISE
        Group Criterion Type
          STANDARD_CRIT
        Bias Type
          BIASED
