Host documentation

[ben-albrecht]

Host chpldoc-generated documentation, possibly utilizing https://pages.github.com/ in a docs/ directory.

Ideally, CI (Travis?) could build and update this documentation for every PR.

If using github pages, don't forget to add a .nojekyll file.

Thank you Ben. I will organize the doc because my personal website is hosted in github pages. I will make it as subfolder project.
I will notify you when things go on.

@ben-albrecht, I did not forget this issue. I am getting an error in the RST compiling. This is occurring because I forgot some comma in the comments.
When I port the ORM to MySQL and SQLite I will document it and close this issue.

Looks great @krishnadey30 - How about I create a gh-pages branch on cdo repo and you can push the built docs to there?

[ben-albrecht]

I have pushed your docs to marcoscleison/cdo/gh-pages, but unfortunately I do not have admin permissions for the repo to flip the switch and enable github pages. @marcoscleison - would you be able to do that?
