Description: 
The Box class implements a 
Region which represents a box with sides parallel to the
axes of a 
Frame (i.e. an area which encloses a given range of values on each axis). A
Box is similar to an 
Interval, the only real difference being that the Interval class
allows some axis limits to be unspecified. Note, a Box will only look like a
box if the Frame geometry is approximately flat. For instance, a Box centred
close to a pole in a 
SkyFrame will look more like a fan than a box (the 
Polygon
class can be used to create a box-like region close to a pole).
