Constant formula cells, better lens support, performance
Formula cells that cannot change will be tagged as constant:
Added the constant field to the Cell type.
Added the constant? predicate which returns the cell if it is a formula cell and it depends only on values and/or other formula cells that are constant.
Better support for lenses:
Added arity to formula function to accept lens update function.
Added arity to set-formula! function to accept lens update function.
Added arity to set-cell!= macro to accept lens update function.
Various performance improvements:
Cell type fields are now native JS arrays, not CLJS collections.
Replace CLJS priority map used in propagation with a sorted JS array.
Eliminate seqs wherever possible by looping instead.
Remove redundant operations during cell creation.
Add simpler, more efficient impl. for simple cell-doseq use case.
Misc:
Add docstrings for everything.
Use clojure.core/destructure instead of cljs.core/destructure when compiling in an older version of CLJS that does not have it.
