113		Here is an outline for the order in which the different routines are called in the program, and what they do. The Arabic numerals give the order of operations in the main program and time iteration parts of the program, and the lower case Roman numerals give the order of operations in the subroutine "Get Fluxes", which loops through the cells on the grid. The 2nd set of Roman numerals should actually read: iv, v, vi, but trac is getting confused.

This subroutine (SR) loops through i=1,mx and checks whether the cell center ((i-0.5)*dx) is to left or right of discontinuity (x0), and then assigns appropriate value to that cell. (All initial conditions for the tests in Toro consist of a left and right state separated by a discontinuity.
