Count the number of non manifold edges in a mesh, e.g. the edges where there are more than 2 incident faces.
Note that this test is not enough to say that a mesh is two manifold, you have to count also the non manifold vertexes.

Check if the given mesh is regular, semi-regular or irregular.
Each vertex of a regular mesh has valence 6 except for border vertices which have valence 4.
A semi-regular mesh is derived from an irregular one applying 1-to-4 subdivision recursively. (not checked for now)
All other meshes are irregular.

Very simple test of water tightness. No boundary and no non manifold edges. Assume that it is orientable. It could be debated if a closed non orientable surface is watertight or not.
The rationale of not testing orientability here is that it requires FFAdj while this test do not require any adjacency.

GENUS.
A topologically invariant property of a surface defined as
the largest number of non-intersecting simple closed curves that can be
drawn on the surface without separating it.
Roughly speaking, it is the number of holes in a surface. The genus g of a closed surface, also called the geometric genus, is related to the Euler characteristic by the relation $chi$ by $chi==2-2g$.
The genus of a connected, orientable surface is an integer representing the maximum number of cuttings along closed simple curves without rendering the resultant manifold disconnected. It is equal to the number of handles on it.
For general polyhedra the Euler Formula is:
V - E + F = 2 - 2G - B
where V is the number of vertices, F is the number of faces, E is the number of edges, G is the genus and B is the number of boundary polygons.
The above formula is valid for a mesh with one single connected component. By considering multiple connected components the formula becomes:
V - E + F = 2C - 2Gs - B -> 2Gs = - ( V-E+F +B -2C)
where C is the number of connected components and Gs is the sum of the genus of all connected components.
Note that in the case of a mesh with boundaries the intuitive meaning of Genus is less intuitive that it could seem. A closed sphere, a sphere with one hole (e.g. a disk) and a sphere with two holes (e.g. a tube) all of them have Genus == 0
