As per our discussion, we should put the information in different channels. E.g. one channel for agent levels, one channel for food, and one (0s or 1s) for impassable/out of bounds. |

Implemented new observation scheme (set via environment argument) which defines a 2D observation grid centered around the agent.
Naming of environments with keyword
-gridcombined with-Xsto define to sight of agents. E.g.Foraging-grid-2s-8x8-2p-2f-v2for agents to observe a 5x5 grid centered around the agent.Each observed cell contains of 5 values. The first 4 encode the entity (out-of-bounds, empty cell, food, agent) and the last value encodes the level (-1 for OOB/ emtpy and level for food/ agent).
