New tutorial section: debugging with IPython

[astrojuanlu]

My colleague @lrcouto did some extensive research on debugging techniques for IPython and for now we've added those to the Kedro docs, but we wanted to ask if you'd accept a PR with a new section under "Tutorial" called "How to debug with IPython". Could include:

• %debug for interactive debugging
• %pdb for postmortem debugging
• %run for running specific files
• Some cool GIFs
• An (i)pdb cheatsheet:

Command	Description
list	Show the current location in the file
h(elp)	Show a list of commands, or find help on a specific command
q(uit)	Quit the debugger and the program
c(ontinue)	Quit the debugger, continue in the program
n(ext)	Go to the next step of the program
<enter>	Repeat the previous command
p(rint)	Print variables
s(tep)	Step into a subroutine
r(eturn)	Return out of a subroutine
b(reak)	Insert a breakpoint
a(rgs)	Print the argument list of the current function

This is a really good idea! We could point to it from the Spyder docs too.

%debug for interactive debugging
%pdb for postmortem debugging

If I'm not mistaken, you can also use %debug for interactive, postmortem debugging.

I stand corrected, thanks Carlos!

This sounds great, @astrojuanlu ! Thrown in u(p) and d(own) for navigating a postmortem stack, and ! for executing arbitrary python code, which for some reason in not in help (like !1+1), and you've got yourself a deal!

I guess there might be a concern with the size of the gifs, so I guess we would want to be mindful of not blowing up the size of this repo, also since those wouldn't work in PDF output of the docs, for example.
