struct gum::KTBNInference< GUM_SCALAR >::_Window_

A compiled window: the junction tree of \(H_t = I_{t-1} \cup V_t\), rooted at the clique holding \(I_t\), plus everything needed to fill and message-pass it. Built once; windows 0..k-2 are the initial ones, window k-1 is the repeating one, re-entered from slice k-1 on.
