* Modified multiple regression newSample methods to ensure that by default in all cases,
...
regression models are estimated with intercept terms. Prior to the fix for this issue,
newXSampleData(double[][]), newSampleData(double[], double[][]) and
newSampleData(double[], double[][], double[][]) all required columns of "1's"
to be inserted into the x[][] arrays to create a model with an intercept term;
while newSampleData(double[], int, int) created a model including an intercept
term without requiring the unitary column. All methods have been changed to
eliminate the need for users to add unitary columns to specify regression models.
* Improved javadoc
