Extending Continuum mechanics module: Introducing classes for Cables and Improving the Truss class

The project aims at Extending the continuum mechanics module. The primary aim of the project is : 1) Improving methods for Truss class - The project will aim to improve Truss class by optimizing its methods and adding some new functionalities. 2) Introducing Cables class - Cable, another important structure in continuum mechanics, will be implemented in this project as a class. This would extend the module and add to the list of structures which already include truss and beams.
