This is a simple Python application that simulates the spread of a virus within a population.

Beyond the given specifications for this assignment, a few things were added:

• A spatial hash table to improve the performance of collision detection
• A static class to generate color gradients between a given start and end color
• A base Virus class which can be subclassed to create viruses compatible with this application, and which was used to add the following:
  • RainbowVirus, a virus which infects people with a synchronised animation through the colours of a rainbow
  • ZebraVirus, people infected with this virus individually alternate between black and white
  • ImmunisableVirus, people who are cured of this virus cannot be infected by it again
  • ZombieVirus, people infected by this virus will chase after people who aren't infected by any virus
  • SnakeVirus, a virus which forms a snake with those infected by it that chases after people who aren't infected by any virus
