//| Purpose: shade New York or other sessions for chart time frames |
//|        M1 to H4 (at a push).                       |
//| version: 2 - enhanced for speed but with MT4 beeing so fast no   |
//|         difference will be noticed, all the sessions are    |
//|         shaded in the init(), last session if it is current |
//|         is widened in the start() in lieu of repainting all.|
