Features
- New (but still experimental) user interface for computing on
multivariate normal distributions.
- Explain cond\_mvnorm a bit better in the vignette.
- Add the possibility to compute log-likelihood and score
functions for permutations of variables (function deperma) and
explain the derivation of the gradient in the vignette.
- Add chol and invchol classes, mainly to avoid confusion.
- Make sure logdet(standardize()) is finite, always.
Bugfixes
- Names didn't propagate properly in several places.
- Allow character subsets.
