powergrasp 0.8.2

compress graphs with answer-set-programming

# PowerGrASP
Graph compression.

Note that this is a full reimplementation of PowerGrASP,
taking advantage of ASP and Python lifting and simplifications.
For the version published in 2017, see [this repository](https://github.com/aluriak/PowerGrASP-1).

On random error, try adding `--no-cache-dir` somewhere.


## TODO
- [x] unit tests
- [x] CLI
- [x] run on big graph
- [x] search multiple motif in the same run (speed up observed on bio graph)
- [ ] timers for solving, full run, extraction, output writing
- [ ] technical documentation
- [ ] search and specific compression of trees
- [ ] search and specific compression of triangle-free graphs
