     A collection of functions to examine microarray datasets that
     include spike-ins. In particular, it allows one to explore the
     distribution of spike-ins within the range of possible expression
     values, the relationship between nominal concentration and
     expression, and the relationship between expected and observed
     fold change for different levels of comparison.
