A variant of the unix 'cut' program, with the ability to reorder fields.
tsv-select is a variation on the Unix 'cut' utility, with the added ability to reorder
fields. Lines are read from files or standard input and split on a delimiter character.
Fields are written to standard output in the order listed. Fields can be listed more
than once, and fields not listed can be written out as a group.
This program is intended both as a useful utility and a D programming language example.
Functionality and constructs used include command line argument processing, file I/O,
exception handling, ranges, tuples and strings, templates, universal function call syntax
(UFCS), lambdas and functional programming constructs. Comments are more verbose than
typical to shed light on D programming constructs, but not to the level of a tutorial.
