splines2 0.4.4

New features

• Added the makepredictcall() methods for all available spline basis functions
  to help model.frame.default() create the right matrices when predicting from
  models with terms such as bSpline(), etc. Thanks Zheyuan Li for suggesting
  this feature.
• Added arguments derivs and integal to bSpline() for consistency with
  mSpline() and bernsteinPoly(), etc.

Minor changes

• Made the internal checking procedure more strict to throw an error if any
  internal knots are placed at or outside boundary:
  issue 5.

Bug fixes

• Fixed the predict() method for cSpline objects when scale = FALSE.
