Updating morpho

As new versions of morpho are released, you will likely want to upgrade to the latest version. From the terminal:

If you used homebrew to install morpho, simply type,
```
brew upgrade morpho
```
If you installed morpho manually, and still have the git repository folder on your computer, navigate to this with cd and type,
```
git pull
```
which downloads any updates. You can then follow the above instructions to recompile morpho. It's not necessary to reinstall dependencies, but note that some new releases of morpho may require additional dependencies.
If you no longer have the original morpho git repository folder from which you installed morpho, simply rerun the installation from scratch as above. You shouldn't need to reinstall dependencies.
