pub fn parameter_numbers(program: &Program) -> GeopResult<BTreeMap<String, f64>>Expand description
What the parameters of program come to as it defines them, by the names a
formula reads them by: a number by its name, a table’s columns as
table.column — its steps defining them run on their own (see
crate::parameters::steps::DefineParameters, LookupTable). Fails naming one
that does not come to anything.
