West unit steps
SYNOPSIS¶
package Math::PlanePath::Foo;
use Math::PlanePath;
use Math::PlanePath::Base::NSEW;
@ISA = ('Math::PlanePath::Base::NSEW', 'Math::PlanePath');
DESCRIPTION¶
This is a multi-inheritance mixin for paths which take only steps North, South,
East and West by distance 1 each time. This includes for example the
"SquareSpiral" and also things like the "DragonCurve" or
"CCurve".
The following path descriptive methods are provided

dx_minimum() -1
dx_maximum() 1
dy_minimum() -1
dy_maximum() 1
dsumxy_minimum() -1
dsumxy_maximum() 1
ddiffxy_minimum() -1
ddiffxy_maximum() 1
dir_maximum_dxdy() 0,-1 # maximum South
