Charts by symbol

// Purpose: a report of the workspace by symbol — how many charts each
// symbol has and at which timeframes — and of the panels that are not
// charts. Changes nothing.
// Category: workspace
// Permissions: workspace.read
// Preconditions: a terminal window
// Side effects: none
// Run: in TTT, open the T0 Editor, open this file, grant workspace.read,
// Run.
