Bubble class abstract

A Bubble is a Step that consists of running a builder function, and its returned Step, until it receives the prompt to stop. Then it will run the candidate it got on the execution of itself.

A Bubble can be closed by FlowContext.pop(), FlowContext.close() or by setting the bool leave to true.

• pop() and close() are meant for errors that can occur as part of the workflow inside of the Bubble.
• leave is way to escape the Bubble successfully.

As example, in the Chain step, leave is set to true whenever the length of the steps is reached.
