PR #1308 adds support for computing the temporal Polyakov loops, but doesn't fully support spatial loops. There's no compelling use case for spatial loops right now, but I'll add it...

A thin QR decomposition implemented as an `V^dag V` + Cholesky + `Sigma^{-\dag} V` requires a large batch of temporary storage unless the `Sigma^{-\dag} V`, where `Sigma^{-\dag}` is upper right...

In contrast to the Chebyshev polynomial basis, which is a 3-term recursion, the Newton basis is a 2-term recursion with similar stability properties, in contrast to the generally unstable power...
