/**
* An AOE type that has a center and a radius, and will blast outward and somewhat around corners/obstacles, out to
* the distance specified by radius. You can specify the radiusType to Radius.DIAMOND for Manhattan distance,
* RADIUS.SQUARE for Chebyshev, or RADIUS.CIRCLE for Euclidean.
*
* This will produce doubles for its findArea() method which are greater than 0.0 and less than or equal to 1.0.
*
* This class uses squidpony.squidgrid.FOV to create its area of effect.
