Upgrade FD tracking

Created by: tongtongcao

PR#107 (https://github.com/JeffersonLab/coatjava/pull/107) is for updates of both DC-only and DC-uRWell tracking. As discussed with the software group, updates for DC-only and DC-uRWell tracking should be separated. This branch removes all updates for DC-uRWell tracking so as to remain updates for DC-only tracking.

In the PR, the main updates for forward tracking can be summarized as follows:

1. Moved and refactored KF package from DC reconstruction package group to common-tools package group
2. Improved pattern recognition
3. Reset covariance matrix for seed
4. Reset initial covariance matrix for the second and following iterations in tracking
5. Applied Deterministic Annealing Filter (DAF)
