The Selection Panel provides functionalities to let the
client choose what he/she wants to keep or eliminate. It
shows the component depth, rules applied for this page, rules
applied for this domain, and rules excluded for this domain,
and the tag name, tag ID, and score. The mobilizer gives
three logical mappings and one score-based mapping, which
can be seen on the left side panel as four separate columns. It
will pre-load stored mapping from the database, and preselect
the corresponding checkboxes on the selection panel.
