QueryResolver should contain (wrap) queries #39
Description
Wasvy's dynamic systems make use of a single ParamSet to retrieve queries. Since a ParamSet is accessed by index, the QueryResolver struct exists in Wasvy to facilitate WasmQuery (and other system params in the future) accessing the correct index that corresponds with their query.
Currently when running a system, both a reference to the ParamSet and a QueryResolver are passed separately to the WasmHost (see dynamic_system in system.rs).
Ideally the QueryResolver completely wraps and holds the mutable reference to the queries, so accessing them can only be done through its own interface.
