%description
TrainFastImputation() uses training data to describe a multivariate normal
distribution that the data approximates or can be transformed into
approximating and stores this information as an object of class
'FastImputationPatterns'. FastImputation() function uses this
'FastImputationPatterns' object to impute (make a good guess at) missing
data in a single line or a whole data frame of data.  This approximates
the process used by 'Amelia' <https://gking.harvard.edu/amelia> but is
much faster when filling in values for a single line of data.
