The Any class is a special Hedge that always returns `1.0`. Its
position with respect to the other hedges is last in the ordered set
(Not, Seldom, Somewhat, Very, Extremely, Any). The Antecedent of a Rule
considers Any to be a syntactically special hedge because it is not
followed by a Term (e.g., `if Variable is any then...`). Amongst hedges,
only Any has virtual methods to be overriden due to its particular case.
