22.05

Multi-functions, paragraphs 7.24-7.28.
Intersection of Manifolds, paragraphs 2.12, 3.18, 3.19, 3.20.
Overlapping meshes, paragraph 3.21.

22.04

Implement specific garbage collector for FiniteElements and Integrators.
We can declare and use an integrator without bothering with the subjacent finite element,
see paragraphs 1.1 and 6.2 in the manual.
Add Mesh constructor with tag::quadrangle, tag::winding, tag::singular, in the spirit of paragraph 7.16.

22.03

Fix nasty bug in progressive mesh generation. Still not entirely stable, needs more work.
3D torus, made of cubic cells, paragraphs 7.11 - 7.13.
Cell constructor with tag::vertex, tag::of_coords, tag::project.
Zero-dimensional manifolds, paragraphs 2.12 and 7.11.
Change tag::progressive into tag::frontal.
STSI meshes work in an incipient setting.

22.02

In progressive mesh generation, change tag::inherent_orientation into tag::orientation, tag::inherent etc.
Introduce constructor Mesh ( tag::import, tag::msh, "filename.msh"). Rename export_msh to export_to_file. Switch to gmsh version 4 format.
Introduce constructor Mesh ( tag::cube, ... ).
Gather source files under src directory.

22.01

Lagrange finite elements of degree two, paragraphs 6.5 - 6.8 in the manual

21.12

Change 'spin' into 'winding'.
Cone-like quotient manifolds, paragraphs 7.12 and 7.13.
Change CellIterator to Mesh::Iterator, thus exposing one less name in namespace maniFEM.

21.08

minor improvements and bug fixes, particularly a bug in progressive mesh generation

21.07

Introduced iterators centered at a cell, paragraph 9.10 in the manual.
Some examples about remeshing, section 10 in the manual.
