Description: Constructs and analyzes optimal row-column designs for
    mixed-level factorial experiments under square and rectangular field
    layouts. For square field layouts, the package implements direct
    common-factor constructions by first forming two component treatment
    arrays, one for each factor or super-factor, and then combining them
    through a symbolic cell-wise product following Gopinath, Parsad and
    Mandal (2018) <doi:10.1080/03610926.2017.1376091>. For rectangular
    field layouts, the package constructs designs by extracting a balanced
    principal block from a mixed-level block design, treating it as the
    principal column, taking the complete treatment set as the principal row,
    and generating the full row-column design by cyclic modular development.
    The package also includes repair utilities for improving disconnected or
    partially connected row-column designs through bounded treatment-swap
    searches while preserving the row-column layout structure. The package
    provides diagnostic tools for connectedness, orthogonal factorial
    structure, balance, estimability, and selected optimality criteria for
    row-column designs.
