* Correlation coefficient r() was returning NaN if the standard deviation of y was 0 (because all y values were equal) * Added test for calculating linear regression with points containing same y coordinate values

linreg()of points parallel to x-axis.Let me know if I need to do anything else to get it merged. Thanks.
