| 10 | # November 2015 - Leopold Haimberger (University of Vienna): |
---|
| 11 | # - modified method list_files to work with glob instead of listdir |
---|
| 12 | # - added pattern search in method list_files |
---|
| 13 | # |
---|
[6f951ca] | 14 | # February - December 2018 - Anne Philipp (University of Vienna): |
---|
[2fb99de] | 15 | # - applied PEP8 style guide |

---|
| 17 | # - optimisation of method list_files since it didn't work correctly |
---|
| 18 | # for sub directories |
---|
| 19 | # - additional speed up of method list_files |
---|
| 20 | # - modified the class so that it is initiated with a pattern instead |
