These are the functions that were implimented in version 0.0.3:

• Distance
  I created a distance measure based on weights where the weights are inverted so that the highest values cause the "least resistance". This is important as the shortest path might not be the most efficient. Read more about it here.
  
• Closeness
  The distance measure would allow us to calculate closeness in a different way. Read more about it here.
  
• Random reshuffling of weights.
