/**
* The purpose of this snippet is to use "points" that are
* basically coordinate objects that act as locations.
* Designed to be as intuitive and user-friendly as I can,
* this short-and-sweet snippet is a handy little utility.
*
* The x- and y- attributes can be set arbitrarily while
* the z- attribute replaces GetLocationZ() and is there-
* fore readonly.
*
* Type Name: point
*
* Syntax: local point pt = GetWidgetPoint(GetTriggerUnit())
* local real z = GetTerrainZ(GetSpellTargetX(), GetSpellTargetY())
*
* API:
*
* CreatePoint(real x, real y) -> creates a new set of coordinates.
* DestroyPoint(point pt) -> destoys the set.
*
* Point2Loc(point pt) -> if you somehow need a location parameter,
* this provides you with one that does not need to be destroyed.
* Unreliable after a wait period.
* Loc2Point(location loc) -> reverse of the above function call.
*
* GetTerrainZ(real x, real y) -> get the elevation of specified coordinates.
*
* GetSpellPoint() -> user-friendly creator.
* GetOrderPoint() -> user-friendly creator.
* GetWidgetPoint(widget w) -> user-friendly creator.
*
* Textmacros:
*
* //! runtextmacro GetLocationZ("x", "y", "z")
* //! runtextmacro GetZincLocationZ("x", "y", "z")
*
* Object Attributes:
*
* pt.x -> x-coordinate.
* pt.y -> y-coordinate.
* pt.z -> z-coordinate (readonly).
