can you please add the documentation about actions

[datonefaridze]

Hi, can you please add docuentatino what those actions mean? for example, what does this aciton mean:
act: {'pose0': (array([0.49375 , 0.003125 , 0.03997803]), array([0, 0, 0, 1])), 'pose1': (array([0.578125 , 0.015625 , 0.03997803]), array([0., 0., 0., 1.]))}
it's very ambiguous, what those arrays represent
