Strint

Header-only library for providing stricter integer types. Features:

• An integer can always be promoted to a larger type
• If the integer is goinging to be downcasted, a CastException is thrown when the target type cannot store the source value.
• Aliases for common integer sizes are provided in common_types.hpp
• The library has some helper types for portable serialization Integer<...>::typeId() and Integer::typeName(). For platform dependent types, these map to the id of the integer type with exact size, that has the same size that the platform dependent type. For example, on 64-bit Linux systems, Long maps to i64, but on Windows platforms, Long maps to i32
