Massive retooling of FeatureExtraction and Analysis tool -- please see comments / let's meet to discuss these changes ASAP.

- Adjusted build orders in CMakeLists to include the ActionRecord cpp file that's in the Simulator's folder
- Added AgentData convenience class for FeatureExtractor to use
- Did a major revision on the FeatureExtractor to work generally for arbitrary numbers of agents
- Added some comments to the FeatureExtractor where they were missing, along with a few TODO items (let's talk about these)
- Added SkillTable class that provides a few database-like convenience functions to facilitate analysis
- Modified ActionRecord: Removed unnecessary fields, added an "unserializeJSON" function that lets you load an AR from disk.

As of this commit, everything compiles, and the Extractor loads sim output properly, builds the skill table, and doesn't crash.
None of the actual modeling code is being executed at this point.
