Implement a linked list module for stdlib of fortran-lang

I have got this opertunity to contribute to fortran-lang under GSoC. This repository contains all my files and modules that I develop for this project.

Project Aim:

Fortran offers all the ingredients needed for building modules of various data types such as linked-list, maps, binary tree, etc. This project aims to implement a linked list module for stdlib of fortran-lang. I wish to provide a module that can be used “off the shelf” by any Fortran user. The project mainly focuses on implementing the most efficient linked list and not just a simple linked list

Overview of what is implemented in this project until now:

• Implemented a straight forward heterogeneous generic linked list.
• Taken analysis of time to process and perform basic operations.
• You can also find a List of Apis that I plan to implement in future for the project.
• The demo files basically contains the rough work for my project or the linked list modules implemented by some other fortran users which I use for reference.

Currently in progress:

• Implement a list of lists.
• Above mentioned heterogeneous generic linked list will be used as a child list in this.
