How to use the development version of Sympy on Jupyter.

Open a terminal, and type in the following:
git clone https://github.com/sympy/sympy.git: Dev_Version

Once complete you can check your Home tree and you will notice a new Folder called 'Dev Version', now you can open it and create a new notebook in the folder; this folder will run the development version of Sympy once imported. All notebooks from outside this folder will use the default Sympy version.

Alternatively, from the terminal you can create a new notebook in the 'Dev Version' folder through the terminal by typing the following:
mv InsertName.ipynb Dev_Version/

To update the entire folder so it has the latest version, you can go into the terminal and do the following:
cd Dev_Version/
git fetch

If you want to update only specific files you can type in the following:
cd Dev_Version/
git checkout origin/master main.c

Where the remote is called origin and you only want to update main.c.
