Computing square root of sum of squared errors vs square root of mean squared errors #46

Hi, in the paper referenced here: https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=6385773&tag=1, absolute_trajectory_error is defined as the root mean squared error, but instead in the code it is computed as square root of sum of squared errors as referenced below.

https://github.com/uzh-rpg/rpg_trajectory_evaluation/blob/995e584d19712b26539fca6dbf694224eea0f5ba/src/rpg_trajectory_evaluation/compute_trajectory_errors.py#L70

Is there a specific reason for doing this?
