 * Returns a set of variable names that are known at the time of call. This
 * includes names of all shared variables in the {@link Configuration},
 * names of all global variables that were assigned during the template processing,
 * names of all variables in the current name-space, names of all local variables
 * and loop variables. If the passed root data model implements the
 * {@link TemplateHashModelEx} interface, then all names it retrieves through a call to
 * {@link TemplateHashModelEx#keys()} method are returned as well.
 * The method returns a new Set object on each call that is completely
 * disconnected from the Environment. That is, modifying the set will have
 * no effect on the Environment object.
