A simple way to run promises in a sequence.

How to use

See example.js which is a runnable example

There's essentially two ways to run promises. The function expects an array of either type:

• promise
• function returning a promise

Which one to use boils down to:

• should the async operations start all at once
• should the next operation only start when the previous one finishes?

TODO

• better example of exception handling
• tests for when promise rejects
• option to stop on first failure
