### Function Reference: `bim2a_boundary_mass`

Function File: [M] = bim2a_boundary_mass(mesh,sidelist,nodelist)

Build the lumped boundary mass matrix needed to apply Robin boundary conditions.

The vector sidelist contains the list of the side edges contributing to the mass matrix.

The optional argument nodelist contains the list of the degrees of freedom on the boundary.
