+- Change format of nudging options in yaml to separate out the different choices
+  made for nudging:
+  * The nudging method (which can be set as 'false')
+  * The height or height offset where nudging begins
+  * The timescale of nudging
+  * The height over which nudging transitions from inactive to full strength
+  * The shape of the transition profile
+  This requires changing the yaml files for forcing conversion.
+  The format of these yaml files is such that the nudging method determines
+  which of the other parameters can and should be present.
