## Changes to libraries
* The QL class `Block`, denoting the `{ ... }` statement, is renamed to `BlockStmt`.
* The models library now models many taint flows through `std::array`, `std::vector`, `std::deque`, `std::list` and `std::forward_list`.
* The models library now models many more taint flows through `std::string`.
* The `SimpleRangeAnalysis` library now supports multiplications of the form
