* fix(simplify): Allow simplify to work in arrays, objects, and indexing Mostly ArrayNode, ObjectNode, AccessorNode, and IndexNode nodes are simply transparent to simplification -- they simply allow it to occur within subexpressions. Then main exception is that if an array or object is indexed by a constant, the expression can be replaced by the corresponding subitem, e.g. `[3,4,5][2]` simplifies to `4`. This at least partially resolves #1913 (see my latest comment there). * fix(simplify): Resolve operations on constant arrays This involves allowing ArrayNodes containing only constant entries to temporarily convert to Matrix type inside of simplifyConstant, so that function and operator calls can occur on them. I also had to add a special case for the function `size` because it can be computed even on symbolic arrays, since the result depends only on the shape, not the entries. Deals with additional cases of #1913; unclear if there are remaining aspects of that issue on which further work is desirable. * chore: fix alphabetization of dependencies And restores inadvertent deletion of a blank line.
