Module jumper.core.node
The node class.
The node class represents a cell on a collision map. Basically, for each single cell in the collision map passed-in upon initialization, a node object would be generated and then stored within the grid object.
In the following implementation, nodes can be compared using the < operator. The comparison is
made on the basis of their f cost. From a processed node, the pathfinder would expand the search
to the next neighbouring node having the lowest f cost. This comparison is internally used within the
open list heap to quickly sort all nodes queued inside the heap.
