adding docs

[stevevanhooser]

Let's add documentation to the distribution.

Katherine -

I just made a new branch called "docs". It has a file "+mia/+docs/build.m" that I copied directly from vhlab-toolbox-matlab. It needs to be modified a bit so that it corresponds to our package here. One thing that does not correspond is the method for finding the path of the distribution. vhlab-arraytomography-matlab does not have a set of global variables (yet).
So I would find the distribution with:

w = which('mia.docs.build');
[parentdir,fname]= fileparts(w);
[parentparent,fname2] = fileparts(parentdir);
[parentparentparent,fname3] = fileparts(parentparent);

% parentparentparent is the path

The rest of the build file needs little modification. We have basic tools in vlt.docs that build a documentation site like http://vlt.vhlab.org.

There also needs some editing to be done to change the template files in docs:
mkdocs-start.yml has the details of the repo, and index.md, contributing.md, and installation.md should be slightly updated.

If you get stuck, let me know, either by writing here or slack or email.

Thanks!
Steve
