Check the consistency of constraints and item usage.

Use the optimal test design approach by Birnbaum (1968, ISBN:9781593119348) and
van der Linden (2018) <doi:10.1201/9781315117430> in constructing fixed and adaptive tests. Supports the following
mixed-integer programming (MIP) solver packages: 'lpsymphony', 'Rsymphony', 'gurobi', 'lpSolve', and 'Rglpk'. The 'gurobi' package
is not available from CRAN; see <https://www.gurobi.com/downloads>. See vignette for installing 'Rsymphony' package
on Mac systems.
