* XDSG_CONTEXT.CMN

* short-lived convenience values that describe the particular constraints
* of the current context as they apply to the current DSG dataset

* V720 *sh* 5/17
* V760 *acm* 3/20 Flag for case when constraints result in no features
*                 Store axlabp setting when it's changed for a no-feature plot.
