Code Refactoring: Redesign Project

[suhailrehman]

RELIC badly needs a code redesign. Ideally should be completed after #4, and is required before we write APIs for the demo.

Some Ideas / Wishlist:

1. Object-Oriented Design based on Ousterhout's Principles
2. Serialize Algorithm's State and Resume
3. Separate Profiling and Score Computation steps from Graph-Building
4. Just the appropriate data structure to store ranked order of edges and coalesce when components are joined
5. Robust tie-breaking mechanism descriptor and implementation
6. Load dataframes on-demand to improve memory
7. Robust logging with trace and debug logging to file
8. Design should allow for quick API hooks into future RELIC webserver
9. Allow easy implementation of sampling/estimation hooks for the future.
10. Allow for threaded operation for compute-intesive tasks such as distance calculation. Examine JIT and threaded operation to verify actual threading via HTOP
