getDecisionVariablesOfItemForMultipool

<code>getDecisionVariablesOfItemForMultipool</code> is an internal function for
making decision variables for selecting a single item, for the purpose of multiple-pool assembly.

internal

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/>.
