depletePoolConstraint

Creates constraints that assure that every item in the item pool is used
(at least) once. Essentially a wrapper around <code>itemUsageConstraint</code>.

Provides simple functions to create constraints for small test assembly problems
(e.g. van der Linden (2005, ISBN: 978-0-387-29054-6)) using sparse matrices. Currently,
'GLPK', 'lpSolve', 'Symphony', and 'Gurobi' are supported as solvers. The 'gurobi' package is not available from
any mainstream repository; see <https://www.gurobi.com/downloads/>.
