-  Functions and data structures to recode categorical variables into
-  vectors and sub-rows of matrices.
-
-  To fit many types of statistical models, it is necessary
-  to change each value of a categorical variable to a vector with binary
-  entries. These vectors are then stored as sub-rows within a matrix
-  during model-fitting. We need functions and data strucutres to,
-  e.g., map a value, say 'a', of a variable named 'cat_var', to a
-  vector, say (0 1 0 0 0), and vice versa.  We also need to be able
-  to map the vector back to the value 'a', and if the vector is a
-  sub-row of a matrix, we need to know which sub-row corresponds to
-  the variable 'cat_var'.
