I think it'd be nice if: ``` x0 = [3, 4] sampler = pints.HamiltonianMCMC(x0) print(sampler) ``` returned: > "Hamiltonian Monte Carlo sampler initialised at [3, 4]" If `x0` was long,...

Make __call__ check for valid parameter length in various classes

I just got stumped by the following: a = pints.toy.RosenbrockError() a.n_parameters() -> 2 (ok) a([1, 3]) -> 400 (ok) So far so good. Now: a([1, 3, 4]) -> 400 a([1,...

Not sure what's the...
