Types module

The Types module provides tools for managing and inspecting data types in Nelson.

It allows users to query the nature of variables, distinguish between numeric, logical, string, and object types, 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.
