Allow "batch" calls of magic with parameter lists

[psychemedia]

In some cases, it may be useful to run the same experiment repeatedly in the simulator using a parameter sweep.

This means:

• passing a set of parameters to sweep over;
• running the experiment with each parameter set in turn;
• presumably collecting some sort of report metric (eg state of the world, execution time) for each run;
• returning the report list.

Thinks: we can do this already:

• download program to simulator using block magic;
• run program repeatedly via line magic

Example here.

There is an example of how to pass state from a notebook Python shell program into a simulator program here.
