MultiTargetTrack for MFADataAssociator

[jgbos]

Is there an example of creating a multiple target tracker for multi-frame association? I see the example example that doesn't utilize track initiation. I tried to make my own but keep running into issues. I can give more info but wanted to first ask if there was already documentation that I didn't find for this.

So we currently don't have an initiator for states for MFA, but #873 is adding the GaussianMixtureInitiator which will make MFA easier to use. Is this the main issue you were coming up against?
