		 * Constructor for a new <code>Slider</code>.
		 *
		 * @param {string} [sId] ID for the new control, generated automatically if no ID is given
		 * @param {object} [mSettings] Initial settings for the new control
		 *
		 * @class
		 * <h3>Overview</h3>
		 *
		 * A {@link sap.m.Slider} control represents a numerical range and a handle.
		 * The purpose of the control is to enable visual selection of a value in a continuous numerical range by moving an adjustable handle.
		 *
		 * <b>Notes:</b>
		 * <ul><li>Only horizontal sliders are possible. </li>
		 * <li>The handle can be moved in steps of predefined size. This is done with the <code>step</code> property. </li>
		 * <li>Setting the property <code>showAdvancedTooltip</code> shows an input field above the handle</li>
		 * <li>Setting the property <code>inputsAsTooltips</code> enables the user to enter a specific value in the handle's tooltip. </li>
		 * </ul>
		 *
		 * <h3>Structure</h3>
		 *
		 * The most important properties of the Slider are:
		 * <ul>
		 * <li> min - The minimum value of the slider range </li>
		 * <li> max - The maximum value of the slider range </li>
		 * <li> value - The current value of the slider</li>
		 * <li> progress - Determines if a progress bar will be shown on the slider range</li>
		 * <li> step - Determines the increments in which the slider will move</li>
		 * </ul>
		 * These properties determine the visualization of the tooltips:
		 * <ul>
		 * <li> <code>showAdvancedTooltip</code> - Determines if a tooltip should be displayed above the handle</li>
		 * <li> <code>inputsAsTooltips</code> - Determines if the tooltip displayed above the slider's handle should include an input field</li>
		 * </ul>
		 *
		 * <h3>Usage</h3>
		 *
		 * The most common usecase is to select values on a continuous numerical scale (e.g. temperature, volume, etc. ).
		 *
		 * <h3>Responsive Behavior</h3>
		 *
		 * The <code>sap.m.Slider</code> control adjusts to the size of its parent container by recalculating and resizing the width of the control.
		 * You can move the slider handle in several different ways:
		 * <ul>
		 * <li> Drag and drop to the desired value</li>
		 * <li> Click/tap on the range bar to move the handle to that location </li>
		 * <li> Enter the desired value in the input field (if available) </li>
		 * <li> Keyboard (Arrow keys, "+" and "-") </li>
		 * </ul>
