• Add GetMap and Erase methods to Store class.
• Return 0 on Store::Get if we tried to get with an unsuitable type (i.e. tried to get a string value into a numeric variable).
• Update the internally allocated heap object on subsequent Get calls using a pointer, to ensure the same result is returned whether one uses Store::Get(std::string key, T* val) or Store::Get(std::string key, T val).
