**Full Changelog**: https://github.com/mie-lab/trackintel/compare/v1.1.5...v1.1.6

This release adds the final part of the Trackintel data model, namely *tours*. The new functions allows to aggregate *trips* into *tours*, which are defined as a sequence of trips that starts and ends at the same location. Tours can also be read with geopandas or from PostGIS databases now. Furthermore, other functions were improved and the documentation was enriched with more examples.

ENH: Tour generation (287)
ENH: Enable postgis integration for tours (356)
ENH: Enable tours to be generated from_geopandas (348)
ENH: Redo read_geolife for smaller memory footprint (354)

Other new features and bug fixes:
ENH: embed version number (323)
ENH: use pd.Grouper for tracking quality (359)
ENH: Add geom_col for read_csv functions (351)
BUG: Fix reading multiple timezones from postgis (331)

As more and more people start using trackintel regularly in their research work we could identify and fix several bugs leading to an even more stable version of trackintel. Apart from those this release features a significant update for speed and stability for our trip generation algorithm (220) and a better support for the interaction with postgis (264). We also updated our documentation style and we now have links to the source code and a better contrast for our function highlighting (237). Finally, starting from this release our trackintel accessors show the correct docstrings (274).

New features and enhancements:
ENH: Cleaner and faster trip generation (220)
ENH: Copy docstring for accessor methods. (274)
ENH: Update read_*_postgis functions. (264)
ENH: gap_threshold for generate_stps (254)
ENH: Added links to source codes (237)

Bug fixes
BUG: fixed 279 + tests (282)
BUG: Index error in pre_filter_locations (276)
BUG: Fix tripleg generation (283)
BUG: Fix errors occuring in geolife tripleg generation (238)

Release for a major bug fix
**BUG: Fix errors occuring in geolife tripleg generation (238)**

Other new features and enhancements:
CLN: Access geometry via geom_col attribute without renaming (265)
ENH: Added links to source codes (237)
