995efe1ead * 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
* Improved tests

b378a18f8d added the dfp library 
The Dfp class represent the high precision numbers, it implements our existing Field interface and hence each instance is associated with a DfpField that provides the constants at the required precision as well as factory methods. This allowed to remove the compile-time constraint in the library. Users can even use at the same time a field for 20 decimals digits precision and another field for 100 digits precision. Dfp instances with different precision CANNOT be mixed in the same computation (doing so creates a NaN). A few utility methods have been added, like constructors from integral types, isInfinite and isNaN methods, equal has been renames to equals and its signature changed to match the general Object method (a hashcode method has been added too).
