The Types module provides tools for managing and inspecting data types in Nelson.
It provides functions to query variable types, distinguish numeric, logical, string, and object values, and work with specialized types such as sparse or integer arrays.
The module also supports creation of objects and validation of variable names, helping ensure type safety and consistency across scripts and functions.
For C++ extension and embedding code, see C++ value API.
