Added plain text extraction to the build process

You can see what the results would look like in the /text/ directory here: https://github.com/sonofmun/canonical-lat-test/tree/0.0.147

Few comments before I forget :
You should export the list of deepest node instead of the highest (aka the text) thus cleaning up any non text node. You'll still need tei note excluded.

I would avoid using the resolver : il would simply look for xml file that are not cts. That will remove the need of parsing metadata.

I'd prefer that as an option.

Would I get the deepest node by specifying the subreference in the getTextualNode method?
And I am not sure how I can export to plain text without either using the resolver or having to parse the file myself? In interactive_text.export(Mimetypes.PLAINTEXT), interactive_text needs to be MyCapytain.resources.texts.local.capitains.cts.__SimplePassage__. And since this is part of the build script, I think I need to reload the collection in order to use CapiTainS to extract the textual nodes, thus the resolver. Is there a better way to do this, e.g., to carry Repository over from hooktest to hooktest-build? Or am I completely missing the point, somehow?

1. List all files that are not cts.xml
2. Initiate a text = CapitainsCtsText
3. Retrieve references : reffs = text.getReffs(depth=len(text.citation))
4. Retrieve passages : passages = [text.getTextualNode(passage) for passage in reffs]
5. Export passages to text.

Stupid. I used my local paths to load some files in the tests. That is why it failed. I will correct it and push the new version.

I need to test the exception on the plain_text function. Also, I think I need to specify the exception more closely. But I honestly don't remember what the error was that I was trying to catch.

[sonofmun]

I remember now. The exception I was getting was when using the resolver and there being a file mentioned in the metadata that didn't actually exist in the file system. I will remove the try, except statement and repush since I am no longer using the resolver.

All great and nearly ready to merge except :

• Build class init documentation has not been updated
• CHANGES not updated
• Bump minor version (second number) because addition to the code base ;)

[PonteIneptique]

Hey !
I actually missed one last thing : could you add a section to the readme for this new "method" ? I don't see the build shown there :)

As I said in the text for the commit:

I didn't add very much since the scope at this point is fairly limited. I simply added it into the flow of prose for the `.travis.yml` file for now. Once I add the `txt`, `csv`, and `json` parameters, I will add a whole section for hooktest-build.
