Merge pull request #21 from srcarter3/master

Changes made to support automatically build and deployment of documentation website

Add a new directory and yml file for the auto-build/deployment:
.github/workflows/ dir was created
sphinx_build_deploy.yml was created which is triggered when a change is made to the docs/ or examples/ directories. This action builds the html pages using sphinx and then deploys them to our webpage by pushing them into the gh-pages branch

Updated the docs/requirements.txt file to include numpy so sphinx can build all the pages properly

Modified the index.rst page to have some of the environment install instructions in code blocks instead of a bulleted list

Updated notebooks to have the '%matplotlib inline' call after the imports in the code so that the webpage renders properly:
Colored_Surface_Tempertature_Plot.ipynb
METAR_Station_Plot_with_MetPy.ipynb
Regional_Surface_Obs_Plot.ipynb
