Indexes allow associating extra data with nodes in the AST using an array and then quickly looking up the array to fetch the extra data. - Index eidx for expressions - Index sidx for statements - Index qidx for queries. AST nodes are not cloneable. Therefore once a module is created, it is not possible to accidentally create two nodes with the same index inadvertently via clone. Also added IndexChecker in debug builds. When a module is parsed, it will assert that indexes have been constructed correctly. AST Cleanup - Make literal expressions (null, val, number, string etc) also structs to match all other expressions - Merge True and False nodes into a single Bool node. Also update dependencies.
