                                           ColumnGrammar

A grammar that builds rowdicts out of character index ranges.

This works by using the colRanges attribute like <col key="mag">12-16</col>, which will take the characters 12 through 16 inclusive from each input line to build the input column mag.

As a shortcut, you can also use the colDefs attribute; it contains a string of the form {<key>:<range>}, i.e., a whitespace-separated list of colon-separated items of key and range as accepted by cols, e.g.:

       <colDefs>
               a: 3-4
               _u: 7
       </colDefs>
