tutorial fixes from #336. Wheels with cuda10.1.

Summary:
Add a document to explain how to run the tutorials.
Fix API of TexturesVertex in fit_textured_mesh.
Prepare cuda 10.1 wheels (not 10.2) for linux to be available on pypi - this matches what colab has.
Change the tutorials to use these new wheels.

+# Tutorial notebooks
+
+For current versions of the tutorials, which correspond to the latest release,
+please look at this directory at the `stable` tag, namely at
+https://github.com/facebookresearch/pytorch3d/tree/stable/docs/tutorials .
+
+There are links at the project homepage for opening these directly in colab.
+
+They install torch, torchvision and PyTorch3D from pip, which should work
+with the CUDA 10.1 inside a GPU colab notebook. If you need to install
+pytorch3d from source inside colab, you can use
+`!pip install 'git+https://github.com/facebookresearch/pytorch3d.git@stable'`
+instead.
+
+The versions of these tutorials on the main branch may need to use the latest
+pytorch3d from the main branch. You may be able to install this from source
+with
+`!pip install 'git+https://github.com/facebookresearch/pytorch3d.git'`.
