/* ParameterPosition
Represents on position in the player input holding a parameter. That
position is filled with some words from the player, those words must
be disambiguated to one or more instances. There are three cases:
1) words presuming it would be a single instance (it
might actually not be) "the chair"
2) words indicating explicit mentioning of multiple instances, "the
book and the chair"
3) implicit multiple using "all" or "everything except the blue
ball"
For all those cases the position must be able to deliver the words,
possible explicit or implicit multiple, and the resulting set of
instances.
