In curve: Dynamic Systems Estimation - Curvature Extensions

# Tests of DSE curvature functions (previously dsecurvature.function.testsB )

# comparison values come only from a previous run of the 
#  code (theoretical values would be nice)...
# Test values have been changed with change to toARMA in 2001.2 which
# eliminates near zero parameter values using fixConstants. The result is
# much more stable and believable curvature results. The span results do not
# change much (as would be hoped) but do change more than the tolerance of 
# these tests. Old values in comments are  strictly for historical reference.
