ThinSincereQuivers :: wallType

wallType -- get the type of a wall for a given quiver



every wall can be represented uniquely by a partition of the vertices Q0 of Q into two sets Qplus and Qminus. We denote the wall W by the subset of vertices Qplus used for defining it.

The type of the wall is defined as (t+,t-) where t^+ is the number of arrows starting Qplus and ending in Qminus, and t- is the number of arrows starting Qminus and ending in Qplus.
