<code>makeTestCluster</code> is a function for creating a <code>test_cluster</code> object.
This is used to make all necessary data (e.g., item information, response data) prior to the main simulation.
This function is only kept for backwards compatibility.

Uses the optimal test design approach by Birnbaum (1968, ISBN:9781593119348) and
van der Linden (2018) <doi:10.1201/9781315117430> to construct fixed, adaptive, and parallel tests.
Supports the following mixed-integer programming (MIP) solver packages: 'Rsymphony',
'highs', 'gurobi', 'lpSolve', and 'Rglpk'. The 'gurobi' package is not available from CRAN; see <https://www.gurobi.com/downloads/>.
