+// CFixBitVec/CBigBitVec *p
+// Pointer to array of non-negative coordinate values.
+//
+// int m
+// Precision of all coordinate values (number of bits required to
+// represent the largest possible coordinate value).
+//
+// int n
+// Number of dimensions (size of the array *p).

+// CFixBitVec/CBigBitVec &h
+// Hilbert index of maximum precision m*n.
+//
+// int *ms
+// Array of precision values, one per dimension.

+// FOR COMPACT HILBERT INDICES
+//
+// CFixBitVec/CBigBitVec &hc
+// Compact Hilbert index of maximum precision M.
+//
+// int M
+// Net precision value, corresponding to the size of the compact
+// Hilbert code.  If not provided, defaults to zero and will be calculated

+// int m
