Detailed Description

Class for measurements of Fourier-transformed velocities in MPC fluids that consist of chains of arbitrary size.

All chains are assumed to be of the same length.

The particles that belong to one chain are assumed to be adjacent to each other in memory. E.g. chain 0 consists of particles [0,n-1], chain 1 of particles [n,2n-1], etc.
