initialize()
Creates a new instance of the data.base class. The data.base class is a
super class that can be extended by different sources of data. We
created this class to allow the OSL to both be able to read from a data
that origiginates from a stream, as well as data originating from a
data.table
or other source.
getNext()

observations from the underlying
data, depending on the implementation this could be a number of rows
from a data frame, or a number of observations from a stream. Note: this
