Release (#278)

* dependency

* Update history.py

> Added the self.time_stamps() method code for HistoryHdf5 class into the __init__() method so that time_stamps are only calculated once as self._time_stamps
> Edited self.time_stamps() method to return self._time_stamps
> Greatly improves efficiency of retrieve() method as time_stamps is not computed each time a new time-point is loaded.

* Solving mesh collision (#263)

* Fix for Issues #261 - cell division failed at the border

* Fix Mesh creation

Surface mesh create wasn't create all faces. Now it is fixed. 
Also : -add two methods to Mesh to list faces and vertices. 
           -generalised coordinates
           -add `write_polygon_mesh` to export mesh into .ply to visualised with blinder

* Add 2D collision solver

Add class to solve collision in 2D or in 3D. 
3D collision solver need to be fixed

* Update README.md

Add `How to cite` section
Add `Geometry` section
Add `Publications` section
Update bibliography link

* Generalised wich vertex penetrate face

* Attempt to set out particular cases

* Detect and fix self-crossing face

Unable to make this algo works... https://europepmc.org/article/PMC/3660981
Use ordered vertices and their angle position.
     -> uncrossed face : angles are monotonically increasing
     -> crossed face : angles are not monotonically increasing

* Use `.apply()` 

Need to recalculate angle_e for twisted face
One fix which is only suitable for 2D lateral sheet...

* ENH: write `mean_XX` method in `Epithelium` class (Issue #224)

* Fix according to comments

* Fix Issue #258 ax argument not considered in `plt_draw.sheet_view`

* ENH: pass column name to `data_at_opposite` issue (#245)

* Add publication and remove bibtex reference

* Add check face convexity

* Use reset_index and code simplification

* yAdd to_mesh function (issue #221) and some test

* Remove the use of reset_index in face_self_intersect

* use ipv_draw with 2D data

* Fix solution after detection point inside polygon

* Remove solving collision for 2 same face...

* Abord vertex displacement if it creates twisted face

* New way to calculate the position of "penetrate" vertices

For now, it is the best way to fix collision (compare to what I tried before). So when a vertex is inside an other face. It is pullback by 10% of the length of the ([v-f1]+[v-f2]/2). with v, f1, f2 position of vertices and center of face 1 and face 2, which are the faces to which the vertex belongs.  It is not perfect and very arbitrary for now, but it avoids vertex displacement at strange place.

* WIP - use force field to fix collision

* Small fix

* Remove function duplication due to circular import

* Calculate "repulsion" gradient in the effector method. Remove loop

* Fix tests

Remove collisions tests
Fix method call in meshes test
Comment "update_repulstion" method in planar geometry

* Add lateralsheet shapes + test

* Update publication + add collapse texte

* Add test for Repulsion effector

* Add test update repulsion

* Remove unused import

* Add `drop_face` to allow hole (issues #220 and #141) (associate #221)

* Update readme.md

* Update publications in README.md

* Add `lineage` attribute to `Epithelium`

In order to keep track of cell lineage

* Remove memory oscillation

* dependency (#277)

* bug fixes
