(Not recommended) Assemble boundary condition contributions

`assemb`

is not recommended. Use `assembleFEMatrices`

instead.

```
[Q,G,H,R]
= assemb(model)
```

```
[Q,G,H,R]
= assemb(b,p,e)
```

```
[Q,G,H,R]
= assemb(___,[],sdl)
```

As explained in Elliptic Equations,
the finite element matrices and vectors correspond to the *reduced
linear system* and are the following.

`Q`

is the integral of the`q`

boundary condition against the basis functions.`G`

is the integral of the`g`

boundary condition against the basis functions.`H`

is the Dirichlet condition matrix representing*hu*=*r*.`R`

is the Dirichlet condition vector for`Hu = R`

.

For more information on the reduced linear system form of the
finite element matrices, see the `assempde`

Definitions section, and the linear algebra
approach detailed in Systems of PDEs.
