// This is the singleton shaped membership function. It consists of 1 point.
// Singletons are used to represent discreet choices. For example if one of the
// inputs to a fuzzy system was "type of car" we may use singeltons with values
// such as "Ford", "GM", "VW", etc. They are discreet choices there's no fuzzyness
// involved.
