In ilapros/DoubleRobGam: Double Robust Generalised Additive Models

Builder for B-splines basis and penalty matrices typically used in DoubleGam and DoubleRobGam

1	bsp(x, nknots = 15, p = 3, center = TRUE, sm.p = 1, order = 2)

`x`	data vector
`nknots`	number of knots used in building the B-splines
`p`	polynomial degree of the basis
`center`	logical indicator on whether the design matrix should be centered (and it should be the case when more than one covariate enter the model)
`sm.p`	smoothing parameter used in the penalty matrix build
`order`	penalty matrix order
