Instantaneous Diffusion Coefficient

Compute the instantaneous diffusion coefficient (IDC) for each trajectory in the input table. A trajectory is defined by a group of rows (defined by the grouping columns) containing particle coordinates and time information.

The IDC is calculated as 1/4 of the mean of the squared displacements at the minimum time scale, divided by the time difference.
