Update to new SWC template

[brandoncurtis]

In case there is some additional change in #37 that is encumbering its merge, this PR is my attempt at a minimal transfer of the existing contents of this repo in a975469c9053fa1ebf3e6a017199c04b7986597d into the SWC template at swcarpentry/styles@9f34e6e952d0d3ab25df0eef4e65a521d2ba4c88.

I only modified the content where it was necessary to make it compatible with the new formatting guidelines. I have just finished SWC instructor training and I would love to help improve this lesson, but the style should be updated first to match the newest template.

repo maintainers: if this is redundant to #37, my apologies. Please let me know how I can improve this PR and how @vuw-ecs-kevin and I can contribute effectively to this lesson :white_check_mark:

Just to say that I have nothing more to offer in terms of getting the

swcarpentry/shell-extras

material refactored so as to use the current SWC/DC/LC styles template.

All the work for doing that was done in my PR 37, and even that merely mimiced what Greg had done elsewhere and so was already known to be an approach that had been applied to other "old-style" lesson content, with the case for doing it to swcarpentry/shell-extras stated, and even "approved", back in January, however this email, also from January,

http://lists.software-carpentry.org/pipermail/discuss/2017-January/004982.html

which is referred to at the start of PR 37, but which you may not have clicked through to, does offer a reason why nothing, of an "official SWC" nature, has happened within swcarpentry/shell-extrasitself.

Also worth noting, is that parts of the swcarpentry/shell-extras material are being canibalised, in a piecemeal fashion, as noted in my comments about the HPC scaffolding effort, so perhaps there is no longer a view, held by those directing SWC/DC/LC, that such a lesson, one pulling the current set of episodes and other related content, together, is needed, within the "official" curriculum, such as one exists, in which case swcarpentry/shell-extras would seem likely to continue to lie fallow.

As to whether a second PR requesting the same thing as another PR is enough to change/generate an opinion is unclear. however, until an official opinion is actually expressed, one way or another, there is clearly still potential for people, like yourself, to try and do work on swcarpentry/shell-extras, that they might be better advised to use their time for elsewhere, within SWC/DC/LC.

37 was merged, so this is redundant!

Posting/Duplicating this here so that Brandon gets to see it.

I'll probably end up cross-posting between this PR and Brandon's here. or more likely duplicating this comment, but I wanted to point out that what got pulled in by this PR, actually goes a couple of stages further than the mere "Swap to jekyll 2", in that it also contains (should really have been on a seperate branch) some early thoughts I had had about simple changes to the underlying styles template that would allow for a correct navigation of the Lesson content, when viewing offline.

These changes don't affect the L&F of this lesson (one of the nice things about the extra approach), however, anyone cloning it may not be getting exactly what they think they are getting.

If there's a need to back those extras out, then I can look to do that.

FWIW, I decided to develop the "fully offline capable" idea in a standalone lesson that I have since created here:

with the rendered version visble here:

@vuw-ecs-kevin Could you submit a pull request to https://github.com/swcarpentry/styles with the "fully offline capable"? Sorry if you already submited and I lost track of it.
