Mimic real Ants using Ant Colony Optimization

# using Processing IDE
## Ant colony particle swarm optimization
1. All ants should search food randomly from there nest.
2. Each ant should create trail of pheromone after finding food from food source to nest
2. The Pheromone should evaporating after some seconds
3. As the concentration of pheromone or trail from ants nest to food source increases all ants should follow this trail of concentrated pheromones.
4. This trail of concentrated pheromone must shortest path from nest to food source.

It is an extension to https://github.com/CodingTrain/Rainbow-Topics/issues/556

*But I am saying about mimic real ants. I believes it will be a great challenge for you. Sorry for my bad English.*

Inizia esaminando l’issue #556 di Rainbow-Topics collegata e il comportamento richiesto di Processing IDE. Il lavoro completato dovrebbe modellare formiche che cercano cibo partendo da un nido, depositano e fanno evaporare tracce di feromoni e seguono il percorso più breve con la maggiore intensità verso il cibo.

Scritto dal modello di indicizzazione a partire dal testo della issue.
