Network seems to be stable!

- Added ability for watchman to break some edges when the network
starts getting a high clustering coefficient
- Fixed random simulation lockup. Scores were getting to be > 1, caused
by unchecked probability attributes which were also getting > 1. No
idea what caused the actual crash but it doesn't seem to happen anymore.
- Ran a simulation for 100000 ticks without a crash.

To add:
- Need to work in/reset 'stepsSinceGivenUp', add a 'give up attempts'
attr that affects their relapse chance
- Need to add random node picker for influence to mix stuff up slightly
- Tune the add/remove values, try and get the nodes moving a little
more.
- Get repast params in there!
