Maintenance Release
This release fixes a bug leading to segmentation fault errors for the BPR solver.
The bug was reported (by @felixmaximilian) in #61 and fixed by ibayer/fastFM-core#13 .
The release further improves code quality by fixing a fair amount of coding style violations (thanks to @takuti ).
- fastFM has been accepted as contribution to the JMLR OSS track.
