Documentation
A 2D axis aligned square. The boundary_corner defines the lower bound. The boundary_size is the length of any edge of the square.
The boundary is inclusive on the low extent and exclusive on the max extent.
Used to represent both the 0. 2D axis aligned minimum bounding square of an element.
- The boundary of a quadtree element

class HasBoundary s whereSource
A instance of HasBoundary has an axis aligned boundign square defined that entirely encloses - the space represented by the type.

Instances
encloses :: Boundary -> Boundary -> BoolSource
Returns true if the first boundary entirely encloses the second boundary. - This is expected to be reflexive.
