Eclipse Java project

Adding a near-empty Eclipse Java project to the repo, containing:

-> The NumberGenerator class I wrote to generate random numbers as
described in the specification
-> An empty "Ant" class (why not?)
-> A basic package structure:
-> antgame.core - This is where core game logic would go (Ant, Map,
AntBrain etc)
-> antgame.services - This is where miscellaneous, ubiquitous services
would go (helper methods etc)
