* Added fraction accumulator * Added binomial proportion interval computers: Wald, Wilson Score, Clopper Pearson, Jeffreys * Width of intervals for all classes can be set via deviation or confidence_level * Support valarray in histogram::fill * Add fraction and count to user guide Co-authored-by: Hans Dembinski <hans.dembinski@gmail.com> Co-authored-by: Hans Dembinski <HDembinski@users.noreply.github.com>
