10.  abstract class MultiChoiceEnumeration extends Enumeration

    Each MultiChoiceSetting takes a MultiChoiceEnumeration as domain.

    Each MultiChoiceSetting takes a MultiChoiceEnumeration as domain. The enumeration may use the Choice class to define values, or simply use the default `Value` constructor:

    object SettingDomain extends MultiChoiceEnumeration { val arg1, arg2 = Value }

    Or

    object SettingDomain extends MultiChoiceEnumeration { val arg1 = Choice("arg1", "help") val arg2 = Choice("arg2", "help") }

    Choices with a non-empty `expandsTo` enable other options. Note that expanding choices are not present in the multiChoiceSetting.value set, only their expansion.

    Definition Classes
      MutableSettings
11.  class MultiChoiceSetting[E <: MultiChoiceEnumeration] extends Setting with Clearable

    A Setting that collects string-valued settings from an enumerated domain.

    A Setting that collects string-valued settings from an enumerated domain.

    - These choices can be turned on or off: "-option:on,-off"
    - If an option is set both on and off, then the option is on
    - The choice "_" enables all choices that have not been explicitly disabled

    Arguments can be provided in colonated or non-colonated mode, i.e. "-option a b" or "-option:a,b". Note that arguments starting with a "-" can only be provided in colonated mode, otherwise they are interpreted as a new option.

    In non-colonated mode, the setting stops consuming arguments at the first non-choice, i.e. "-option a b c" only consumes "a" and "b" if "c" is not a valid choice.
