Math::PlanePath::Base::NSEW -- multi-inheritance mixin for North, South, East, West unit steps

package Math::PlanePath::Foo; use Math::PlanePath; use Math::PlanePath::Base::NSEW; @ISA = ('Math::PlanePath::Base::NSEW', 'Math::PlanePath');

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

value 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
