* annotate pure values with their value, allowing single mininotation values to maintain their labels as pure * Don't use any 'patternified' arguments if they're all 'pure' * allow pattern weights (roughly, beats-per-cycle) to be inferred where possible, including from mininotation and across many transformations (e.g. `fast` with a 'pure' factor) * Add `beatCat`, similar to `timeCat` but funkier * `silence` has a weight of 1, add alternative `nothing` with a weight of 0, and `gap` function with weight argument * preserve weight across applicative operations (weight comes with the structure) * add `stack` alternatives that take advantage of pattern weights to align patterns differently - `stackLeft`, `stackRight`, `stackCentre`, `stackExpand`, with `stackBy` with an argument for patterning the alignment.
