Read particle positions and nu from a formatted file with the following format:

  1. The first line must contain the integer number of objects for the system, and the particle numbers on each object; each column separated by one tab.
  2. The other lines must contain at least 3 columns with the x, y, z coordinates of the particle positions. An optional 4th column can contain the values of nu on the particles. If the 4th column is not present, nu will be roughly estimated using the density read from the ID and the average volume per particle; the latter is computed by computing the average particle separation along the z direction.
