Add IntegratedBrownianMotion kernel and tests#81
Merged
Conversation
Export a new IntegratedBrownianMotion kernel from NowcastAutoGP, implement the kernel in extension_kernels.jl (scalar and matrix eval_cov, reparameterize, rescale, pretty) with documentation (including relation to cubic splines), and add comprehensive tests validating covariance values, matrix form/PSD, input/output warping behavior, and pretty-printing in test/test_integrated_brownian_motion_kernel.jl.
