Added Haskell code for convolutions

[jiegillet]

I did not add FFT code as it is messy in Haskell AFAIK.
Added my name to contributors :p

[leios]

Looks good! Thanks for sending it in! =)

I'm going to add Haskell to the book.json and describe what I changed there (I link the PR then).

[leios]

@julianschacherpp I thought haskell was already in the book.json?

[june128]

@leios you're right, it is
edit: see below

[leios]

Oh, @julianschacherpp I already made those changes and was going to push them in just a second. I realized the julia tags were also incorrect.

[leios]

I needed to add a small text blurb around the fft-based julia implementation.

[june128]

@leios ok, perfect :)

[leios]

Done. Thanks @jiegillet and @julianschacherpp !

You guys rock! =)

Thanks guys. I tried to mimic what I saw on another page (FFT I think), maybe I got it wrong ^^

[june128]

@jiegillet the multiple languages with that book.json is quite new and we're missing documentation on that... so it's basically our fault :)

edit: @jiegillet did everything right, the rest of the statement is still true

[leios]

@jiegillet To be fair, the name change from haskell to hs doesn't change too much, it just standardizes everything and ensures that we have syntax highlighting enabled for the language. I had to change my julia tags to jl because I forgot about it too.

The only other change was just to make sure there was some code available in the fft box when people switch to haskell.

What @julianschacherpp said...

[june128]

ohh, I was a wrong... that you didn't wrote hs instead of haskell is regarding the include-codeblock plug-in and doesn't affect theme-api at all. So you did everything about the theme-api right. That you used haskell instead of hs isn't really important, because this include-codeblock uses this table: http://highlightjs.readthedocs.io/en/latest/css-classes-reference.html#language-names-and-aliases
So it's basically just standardization like @leios said.

I were wrong, sorry.

@jiegillet me confused, see above, in case you didn't see my comment; sry
