Created fly_towards_middle.yml which is data for two stationary boids at the origin and 1,1 respectively.
Fixed the format of fly_towards_middle.yml
Added test_fly_towards_middle() to the tests we can run. This tests checks whether the velocity of one of the boids is properly changed by another boid.
Slightly changed test_fly_towards_middle() so it actually works properly with two boids.
Created sample_distance.yml which will be used to check that the distance method works as expected.
Created test_distance() which is a function that will test that the distance function works as expected.
Created the sample for the fly_away_from_nearby test.
Created the test for fly_away_from_nearby.
Created some sample data from which the boids to test match_speed will be created.
Created a test which tests the match_speed method.
Changed the .yml for fly_towards_middle so it contains the before and after data.
Changed test_boids to account for the change in fly_towards_middle.yml
Changed sample_fly_away_from_nearby.yml to contain the after states as well.
Changed the test_fly_away_from_nearby to work with the changes in the corresponding .yml
Changed sample_match_speed.yml to contain the before and after data.
Changed test_match_speed to work with the changes to the corresponding .yml
