This class defines a logically grouped set of variables in the system.
VariableGroup
is appropriate for representing several unknowns in the problem that are all approximated with the same finite element approximation family and (optionally) a list of subdomains to which the variables are restricted.

Constructor.
Omits the subdomain mapping, hence this constructor creates a variable which is active on all subdomains.
Definition at line 201 of file variable.h.

Constructor.
Takes a set which contains the subdomain indices for which this variable is active.

Appends a variable to the group.
Really only can be used by System
in a very limited window of opportunity - after the user specifies variables but before the system is initialized.
