The numeric-units parser will load data from a column in a source data table and map values to other values before producing a numeric variable within a collection.
It inherits attributes and behaviors from its parent: parser - numeric.
The numeric-units parser will parse a column value containing a number and a units string, and will extract the number part to become a variable within a collection.
