Claim: MSR ActionPairs dataset

[prabhanjan-jadhav]

This issue claims to add MSR ActionPairs dataset:

This is a 3D action recognition dataset, also known as 3D Action Pairs dataset. The actions in this dataset are selected in pairs such that the two actions of each pair are similar in motion (have similar trajectories) and shape (have similar objects); however, the motion-shape relation is different.
