'  ==========================================
'  Dijkstra's algorithm to find Shortest Path
'  ==========================================
'
' E.W. Dijkstra is a Dutch professor in Computer
' Science, who did a lot of research in graphs.
'
' Dijkstra's algorithm is of use when working with
' directional graphs. It constructs the shortest path
' between a starting-node and a goal-node.
' It is assumed that every link between two nodes
' has a certain cost, and this algorithm finds the
' path between the two given nodes with the lowest cost.
'
' The idea of this VB project was to show the
' work of this algorithm in a visual way.
