auto-shovel pods/scopes that will overlap due to width/height expansion

[forrestbao]

I am trying to use CodePod to develop a real bioinformatics program and I have found a series of pains. This is the first one.

Problem

I spend a lot of time on manually repositioning pods or scopes. This greatly reduces my development speed.

There are two cases:

1. If I expand a scope's width or height, or the width of a pod, manually, pods and scopes in the way do not move away automatically. Instead, they overlap. So I have to first make space for the expansion and then expand.
2. For a code pod, as the code gets longer (thus the height of a pod increases), it overlaps with pods or scopes that were originally below it. Like the case above, I have to manually find spaces again.

Expected change

We do not need fancy auto-layout to solve this problem. Just do auto-shoveling. When the width (height) of a pod/scope expands, automatically push the pods/scopes in the way to the right (down), recursively, so users do not have manually make the space.

For the scope, I really want the automatic bubbling #151 to be implemented so I can save time from manually adjusting the shape the of a scope.

Will a growing pod/scope push other pods nearby away, or we just let them overlap with other peers?

Push them away.
