Returns a character vector listing the variables that currently have recipes
in the system. The variable names will be printed in canonical form, which
means that all letters will be converted to lowercase, and all
non-alphanumeric characters will be replaced with _
s. Names of
variables requested for output by users will similarly be converted to
canonical form. Users can take advantage of this to make the variable lists
in their input more readable. For example, the variable with canonical name
gdp_mer_
can be represented as GDP(MER)
in input files.

Processing the data for a variable is done in a function called
module.varname, for example, the variable gdp_mer_
is processed in
module.gdp_mer_
. The documentation for these functions
contains a list of the columns in the raw table produced by the function,
prior to aggregation or filtering. This information is potentially useful
for planning filtering or aggregation operations. The module documentation
will also have any notes pertinent to the computation of the data.
