Description: Gradient projection algorithms for orthogonal and oblique rotation
    of factor loadings matrices in factor analysis. Implements a comprehensive
    set of rotation criteria including quartimax, quartimin, oblimin, geomin,
    simplimax, the Crawford-Ferguson family, and target rotation, among others. 
    Supports multiple random starts. For details see Bernaards and Jennrich (2005)
