+/* This is an implementation of the adaptive Monte-Carlo algorithm
+   of G. P. Lepage, originally described in J. Comp. Phys. 27, 192(1978).
+   The current version of the algorithm was described in the Cornell
+   preprint CLNS-80/447 of March, 1980.
+
+   This code follows most closely the c version by D.R.Yennie, coded
+   in 1984.
+
+   The input coordinates are x[j], with upper and lower limits xu[j]
+   and xl[j].  The integration length in the j-th direction is
+   delx[j].  Each coordinate x[j] is rescaled to a variable y[j] in
+   the range 0 to 1.  The range is divided into bins with boundaries
+   xi[i][j], where i=0 corresponds to y=0 and i=bins to y=1.  The grid
+   is refined (ie, bins are adjusted) using d[i][j] which is some
+   variation on the squared sum.  A third parameter used in defining
+   the real coordinate using random numbers is called z.  It ranges
+   from 0 to bins.  Its integer part gives the lower index of the bin
+   into which a call is to be placed, and the remainder gives the
+   location inside the bin.
+
+   When stratified sampling is used the bins are grouped into boxes,
+   and the algorithm allocates an equal number of function calls to
+   each box.
+
+   The variable alpha controls how "stiff" the rebinning algorithm is.  
+   alpha = 0 means never change the grid.  Alpha is typically set between
+   1 and 2.
