### Constructing all NE-lattice paths from $(0,0)$ to $(m,n)$

If I consider only Dyck Paths, I can do write something like this:

```
DWS=DyckWords(3).list()
for D in DWS:
print(D.height())
```

to obtain the height of all Dyck paths of length $3$. However, I would like to do the same thing but using $NE$-lattice paths from $(0,0)$ to $(m,n)$. Is there an easy way to do this in Sage?
