Step by step execution (maybe with variable "watch") #223

Closed GoogleCodeExporter closed 8 years ago

For educational purposes it is good to see/analyse what exactly happens step by 
step.

may be it would'nt be hard to implement "Step and Pause" button aside "Run" 
(and maybe even breakpoints?). 

A good example is http://pythontutor.com/ (and some tries in 
http://reeborg.ca/world.html)

This is not a Blockly issue, this is an execution issue.  To implement 
step-by-step execution, you'll need an interpreter that can execute code 
step-by-step.

The good news is that we wrote one for JavaScript specifically for Blockly 
educational projects.  Here it is:

Enjoy!

I looked inside apps and found what I wanted... I hacked a bit maze.js -- see 
the "Pause" and "Next Action" buttons :)
