The main functions are:
get.plan: Menu-driven selection of crossover designs
allcombs: Construct crossover design with all possible
treatment orders
williams: Construct a Williams design
williams.BIB: Construct a crossover design based on a
combination of balanced incomplete block designs and Williams designs.
des.MOLS: Construct crossover design based on mutually
orthogonal Latin Squares
balmin.RMD: Construct balanced minimal repeated
measurements crossover design
isCbalanced: Check whether a crossover design is balanced
for first order carryover effects
isGYD: Check whether a crossover design is balanced
