Add seeding script

[bumi]

the seed script allows to execute certain contract function to easily setup testing data for locally deployed contracts to a development chain.

@skddc I need to run that async contract calls sequential. Can I do that somehow differnetly, without the asyc dependency?

[galfert]

@bumi do the contract calls return Promises?

[bumi]

no, they use callbacks, like:

Kredits.contractMethod(argumens, function(err, response) {
  console.log(response);
});

I've tried to wrap that in a Promise but could not get it work to run sequentially.

I think it's possible with some recursive function calling, but it wouldn't look remotely as simple as with async :)

If you really want to get rid of the dependency, I would be happy to give it a try.

[bumi]

nah, I've spent enough time on that. :) thanks! also thought it might work with async/await - but could not get that working either.

[bumi]

I am merging this then.

I think that only works with Promises.
