/**
 * Represents a UI command to reduce the indent of the selected text or paragraph within a rich text
 * editor.
 *
 * 

The {@code OutdentCommand} extends {@link RichTextCommand} and provides users with the ability * to decrease the indent level of the selected text or paragraphs. The command is represented by a * button with an indent decrease icon. When this button is clicked, it reduces the indentation of * the currently selected text or paragraphs. * *

Usage Example: * *

{@code
 * DivElement editableDiv = DivElement.create();
 * OutdentCommand outdentCommand = OutdentCommand.create(editableDiv);
 * }
