Update LaunchOptions description

    /**

     * Class used to specify clipping for a kernel launch.

     * Class for specifying the specifics about how a kernel will be

     * launched

     *

     * This class can specify a potential range of cells on which to

     * run a kernel.  If no set is called for a dimension then this

     * class will have no impact on that dimension when the kernel

     * is executed.

     *

     * The forEach launch will operate over the intersection of the

     * dimensions.

     *

     * Example:

     * LaunchOptions with setX(5, 15)

     * Allocation with dimension X=10, Y=10

     * The resulting forEach run would execute over x = 5 to 10 and

     * y = 0 to 10.

     *

     *
