Cyclic block bootstrapping alternate version about scores

[nikeethr]

From a pedantic view, "cyclic" permutation makes more sense than "circular" from a mathematical standpoint, and in an implementation context. Indices can be cyclic, not circular - which tends to be more of a geometric nomenclature. Though admittedly "circular" is what some reference papers use (in the context of atmospheric science.).

I think it's dependent on the target user, but I prefer cyclic.

I can see it being used in a general context as well e.g. in machine learning.
