	/**
	 * <p>lib_flex_animation_code_10_org_as3lib_kitchensync_easing_Linear produces values that increase in a linear fashion without any accelleration. It simply finds
	 * the percentage complete from the time elapsed to the duration. Since there is no variation in the values
	 * produced, there is no need for multiple easing functions and only <code>ease()</code> is provided.
	 * Visually, this class produces values that cause a subject to move steadily from one point to another.</p>
	 * <p>The easing classes provide static methods for interpolating the change between two values over time.
	 * Each class handles the interpolation, or easing, differently. Each class typically contains three methods
	 *  - <code>easeIn()</code>, <code>easeOut()</code> and <code>easeInOut()</code> - which vary the rate of change
	 *  of the values. Most of the easing functions produce values as a percentage - a number between 0.0 and 1.0</p>
