Update templates.md

[dataPulverizer]

I have replaced the current templates tour with a highly detailed tutorial on generic and metaprogramming in D.

Thanks

This is a decent first draft of a comprehensive survey of metaprogramming topics in D. Unfortunately, that makes it a poor fit for the D tour, which wants short, focused, introductory articles on individual topics.

If you would like to submit any of this content for inclusion in the D tour, please split it into individual pages, each no more than 200 lines in length and focused on a single language feature or programming technique. Some of the material (for example, the part on CTFE) could also be submitted as improvements to existing tour pages.

Thanks a lot for helping out! I don't have time atm to review in-depth, but a first comment: is there a possibility to split this into two or three sections?
At the moment most sections of the tour are roughly one page, so that the user isn't over-whelmed with content.

Okay. I will rework it and split it into a few sections.

@dataPulverizer I think that the following file structure would be the organization that best fits the tour:

tour/
├── ...
├── metaprogramming
│   ├── 00-intro.md
│   ├── 01-ct-sequences-intro.md
│   ├── 02-ct-sequences-algos.md
│   ├── 03-ctfe.md
│   └── 04-string-mixins.md
└── templates
    ├── 00-intro.md
    ├── 01-function-templates.md
    ├── 02-struct-class-interface-templates.md
    ├── 03-enum-templates.md
    ├── 04-alias-templates.md
    └── 05-mixin-templates.md

@PetarKirov

I'm happy to do this but I created a separate PR #342 after cancelling this one. Shall I delete the new PR? I'm happy to do so if it is clearer. I created it because for some reason I didn't realise I could re-submit a different document structure in this PR. From the above comments before yours, I thought people wanted something smaller and more brief, both for each document and for the overall length, which is why the new PR contains a small fraction of my initial PR split over different documents. Shall I reopen and work within this PR so the history is retained? If so I can put the original material into the structure you have specified and do another PR.

Please confirm.

Thanks.
