Made the following changes to pecos/src

ProjectOrthogPolyApproximation.hpp
----------------------------------

Moved functions below from protected to public
  void compute_coefficients();
  void restore_coefficients();
  void increment_coefficients();
  void decrement_coefficients();
  void finalize_coefficients();


SharedProjectOrthogPolyApproxData.hpp
-------------------------------------

Moved functions below from protected to public
  void allocate_data();
  void pre_restore_data();
  void post_restore_data();
  void increment_data();
  void decrement_data();
  void pre_finalize_data();
  void post_finalize_data();
