Error in simulate_k when number of teams are different

[kmcnayr]

In examples/notebook2 I am receiving an error after changing Magmaguard team to a third team name in the starwars-cloneswars.csv dataset.

The issue appears to be due to the battle now containing 3 teams after loading the unit dataset file, but the simulate_battle is only returning a result for the unique teams in M.

Generically: this error happens when the number of unique teams loaded into the battle object is different than the number of teams that are added via create_armies

Solution: I suppose you can just make sure to add armies for all of the teams that are loaded into the battle object.

I found this when playing around with examples/notebook2 which loads a number of units from the csv dataset file but only runs a sim using two unit types which are in three army groups, and represent only two of the three unique teams in the dataset file (after I changed the Magmaguard to a third team name).
