S: A packed spheroids configuration (particle system)
In simLife: Simulation of Fatigue Lifetimes

A dataset containing non-overlapping spheroids where each list element consists of the following variables:

1	data(AL2MC_20p_k10_F2p_S)

A list of length 4905 containing lists each of length six

id the current cluster id
center the center of ball which defines the cluser region
u the orientation vector of spheroid's rotational symmetry axis
acb two shorter semi-axis lengths and major semi-axis length
angles polar angle and azimuthal angle
rotM rotational matrix, center of rotation is the center of the spheroid
interior attribute, whether the spheroid lies in the interior of the simulation box
label attribute, character, user defined label, here: 'P' (particle) or 'F' (ferrit)
area attribute, the projected area
