Description: Constructs screening designs for experiments involving
        continuous and categorical factors with multiple levels. The
        package implements methods for constructing mixed-level
        screening designs, involving factors with more than two levels.
        It also evaluates the statistical performance of screening
        designs throughdev power to identify active effects and Type I
        error rates. The package implements three methods proposed by
        Jones, B., Lekivetz, R., Majumdar, D. and Nachtsheim, C. (2025)
        <doi:10.1080/00401706.2024.2362149> for generating efficient
        screening designs involving three-level continuous and
        two-level categorical factors for even run sizes. It also
        includes Paley Type I and Type II constructions for conference
        matrices and pseudo conference matrices obtained using the
        coordinate exchange algorithm by Jones, B. and Nachtsheim, C.
        J. (2011) <doi:10.1080/00224065.2011.11917841> which are used
        in the development of these screening designs.
