/* 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.
