Table wrapper that removes duplicate rows

Deduplication is based on the visible columns at the time distinct() was called. Uses TreapIndex for O(1) duplicate detection during iteration.

// Unique roles
$table->columns('role')->distinct();

// Unique role+name combos, then project to role
$table->columns('role', 'name')->distinct()->columns('role');
