The base number of knots for zeroth-order smoothness
basis functions. The number of knots by degree interaction decays as
base_num_knots_0/2^(d-1) where d is the interaction degree of the basis
function.
The base number of knots for 1 or greater order
smoothness basis functions. The number of knots by degree interaction
decays as base_num_knots_1/2^(d-1) where d is the interaction degree of
the basis function.
