Nodes and displacements
added flow info to nodes
some reformating
Update README.md
implemented djikstras algorithm to find the smallest distanse of all nodes to the start node. will be used when calculating the layout of the flowchart.
updated with djikstras algoritm
New distance algorithm + node info flowTo

I put the nodes further to the right on the x-axis depending on the
distance. Cleaned up the code a bit, and the new flowTo info about
nodes, which prevents several arrows going back and forth between the
same nodes.
