 Flatland is a toolkit for developing and comparing multi agent reinforcement learning algorithms on grids.
 The base environment is a two-dimensional grid in which many agents can be placed. Each agent must solve one or more tasks in the grid world.
 In general, agents can freely navigate from cell to cell. However, cell-to-cell navigation can be restricted by transition maps.
