Add Jupyter Book TOC and intro; update myst

Add a Jupyter Book table of contents and introductory page: create notebooks/_toc.yml with the chapters list and add notebooks/intro.md with repository setup and Binder/book badges. Update notebooks/myst.yml to the new top-level metadata (title, author, github, logo) and disable notebook execution (execute_notebooks: off), removing the previous 'project' and 'site' structure to match the Jupyter Book / MyST configuration.

+
+This tutorial is made for scientists who want to learn Python and eventually step from Matlab.
+
+Python is a general programming language with many scientific libraries. 
+It is optimized to be easy to develop in. The same is not true for Matlab which is 
+a domain-specific language.
+
+1. Install [Miniforge](https://github.com/conda-forge/miniforge) 
+
+2.  Download this repository:
+
+```
+git clone https://github.com/pnavaro/python-notebooks.git
+```
+
+or download as a [zip file](https://github.com/pnavaro/python-notebooks/archive/master.zip).
+    
+3. Create a new conda environment:
+
+```
+conda env create -f environment.yml -n python-navaro
+conda activate python-navaro  # Linux OS/X
+```
+
+4. If you have an existing installation of Jupyter install the new kernel with:
+
+```
+conda run -n python-navaro python -m ipykernel install --user --name python-navaro 
+```
+
+5. Open notebooks with:
+
+```
+cd python-notebooks
+jupyter notebook
+```
