* Describes a two dimensional wall defined as a line strip and optional maximum and minimum heights.
* The wall conforms to the curvature of the globe and can be placed along the surface or at altitude.
*
* @alias WallGraphics
* @constructor
*
* @param {Object} [options] Object with the following properties:
* @param {Property} [options.positions] A Property specifying the array of {@link Cartesian3} positions which define the top of the wall.
* @param {Property} [options.maximumHeights] A Property specifying an array of heights to be used for the top of the wall instead of the height of each position.
* @param {Property} [options.minimumHeights] A Property specifying an array of heights to be used for the bottom of the wall instead of the globe surface.
* @param {Property} [options.show=true] A boolean Property specifying the visibility of the wall.
* @param {Property} [options.fill=true] A boolean Property specifying whether the wall is filled with the provided material.
* @param {MaterialProperty} [options.material=Color.WHITE] A Property specifying the material used to fill the wall.
* @param {Property} [options.outline=false] A boolean Property specifying whether the wall is outlined.
* @param {Property} [options.outlineColor=Color.BLACK] A Property specifying the {@link Color} of the outline.
* @param {Property} [options.outlineWidth=1.0] A numeric Property specifying the width of the outline.
* @param {Property} [options.granularity=Cesium.Math.RADIANS_PER_DEGREE] A numeric Property specifying the angular distance between each latitude and longitude point.
* @param {Property} [options.shadows=ShadowMode.DISABLED] An enum Property specifying whether the wall casts or receives shadows from each light source.
* @param {Property} [options.distanceDisplayCondition] A Property specifying at what distance from the camera that this wall will be displayed.
*
