Closes #78.

@johnstairs When you are ready, you can follow the additions to README.md to get started with Matlab.

On my Windows PC, where I run my devcontainer in WSL, my WSL shell profile $HOME/.profile looks like this:

export MATLAB_LICENSE_FILE=/mnt/c/Users/username/Downloads/Network.lic.com

Be sure to restart all instances of VS Code before building the devcontainer.

Should we have have the sandbox model generate MATLAB too? In the past, I've found that model to be a useful testbed for isolating problems

[johnstairs]

If you delete a top-level type (like a record or a protocol), we should make sure we delete the associated generated files.

[johnstairs]

MyType: !record
  fields:
    a: int->string

If I create two instances and call a.eq(b), I get

Error using ==
Concatenating 'dictionary' objects is not supported because 'dictionary' objects can only be scalar.

[johnstairs]

MyType: !record
  fields:
    a: int*

If I create two instances of this type where the a fields have different lengths, eq raises an error:

Arrays have incompatible sizes for this operation.

Error in == (line 20)
        all([self.a] == [other.a]);

I don't know if we can customize a class' string representation, but say the default for union is not that helpful:

  Int32OrString with no properties.

This is great, Joe!
