try out jupyter backend as a candidate for documentation engine

[slayoo]

as noted by @GillesDuvert, there exist already a jupyter backend aimed at supporting GDL: https://github.com/lstagner/idl_kernel

Since the repository above is abandoned, maybe it could just be "hijacked" and forked into the gnudatalanguage organization. Or maybe ask @lstagner if he could move the repo to us (and rename).

[GillesDuvert]

Both things are doable. Forking (changing e.g. 'idl' in 'gdl' in the scripts). But also and more important, telling @lstagner about GDL and this issue.

[lstagner]

Go ahead and fork it if you want. However you may be better off starting from scratch since it probably doesn't work with more recent versions of Jupyter anyway.

@lstagner Thanks, let's first try with the fork, here it is: https://github.com/gnudatalanguage/idl_kernel
