[WIP] Restructuring

**WIP**

I'm starting to restructure the project, as currently the state the repo is in at the moment is a bit messy.
I've updated the gruntfile with new tasks and moved it to the root directory.

Maybe it would be better to build the docs with Jekyll, considering it automatically compiles on Github Pages.


### Tasks
- [x] Move Gruntfile to root directory
- [x] Change around file structure
- [ ] Move hardcoded values to variables.less
- [ ] Convert to Jekyll (maybe??)
