R/control.utilities.R
control.list.accessor.RdUtility method that overrides the standard `$' list accessor to disable
partial matching for ergm control.list objects
# S3 method for class 'control.list'

NULL if no matching elements found
Executes getElement instead of $ so
that element names must match exactly to be returned and partially matching
names will not return the wrong object.
