Using pygame, the path visualization program will find a path from the start node to an end node. You can choose a start node and an end node by yourself! You can also add and delete blocks! Needs pygame module to work!!

Note: A-star is a little bit inconsistent since the priority queue will not let different nodes with same fScore into it. I have added a tuple of (fScore, count, node) into it. The count variable will decrease as the path is more traversed. This makes the priority queue to compare the same fScored node with count and that has less count value will take more priority!

Better method to remedy this situation will be appreciated!
