""" Class
Name: Cell
Description: Basic unit of a Grid environment
Fields:
 - filled - whether the cell is an obstacle, for use in certain environments
 - x, y - coordinates within the associated Grid
 - visited - for usage in search traversals if done later
 - neighbors - list of neighbors, edge representation
 - g - path cost value, for use in search algs
 - h - heuristic value, for use in search algs
Functions:
 - only the magic functions
