Allow copy/paste from analyzer to some other document storage medium

[sievers2501]

Currently, when I copy my system to another application to save it, and then copy it back, the indent level is always destroyed. In Google docs, it pastes over as all one level with no indentation. In word, it pastes over fine, but when you try to copy it back it flattens it again. I also tried notepad just in case with similar results.

Alternatively, I need a way to save the system directly in the tool.
