Geometry
Construct a LatticeInfo based on positions for corners 0, 1, and 3. Each corner will
have x and y positions provided and a check will be made on the positions to ensure that
they represent a rectangle.

Construct a LatticeInfo based on positions for all corners contained in X and Y arrays.
Some of the data in the arrays will be redundant since not all four corner positions are
needed to define a LatticeInfo object. The corner locations will be computed from the
4-170 Ocean Application Development Framework 2008.1
