+    // The axisConversionArray, when given a primary index, allows easy
+    // access to the indices of the other two axies.  Access the data at the
+    // primary index location to get the horizontal secondary axis.
+    // Access the data at the primary location plus three to get the
+    // remaining, tertiary, axis.
+    // All directions are specified by an index, 0, 1, or 2 which
+    // correspond to x, y, and z.
+    // The axisConversionArray is used in several places
+    // notably the crossection and taperedLimb methods.
+    // Example:
+    // If the primary axis is z, then the primary index is 2.
+    // The secondary index is axisConversionArray[2] which is 0,
+    // the index for the x axis.
+    // The remaining axis is axisConversionArray[2 + 3] which is 1,
+    // the index for the y axis.
+    // Using this method, the secondary axis will always be horizontal (x or z),
+    // and the tertiary always vertical (y), if possible.
