FOR THE INDIVIDUAL TREE RING SERIES (VS-Lite grows 10 "trees" at each
site using semi-randomized parameters for each)

example from: esper_trwz_mpiE1_ens01_02.1850.txt <==

One line header gives: number of years, number of sites, and randomization number (of 10)

Other lines give: year, site, latitude, longitude, normalized tree-ring width (mean
0, standard deviation 1) for each site and randomization number).
