If the developer forgot to call ArgumentParser::parse_args<>, attempts to
use ::get, ::present, etc., would raise "No value provided...". With this
change, the error better describes what went wrong.

As the user did not include the argument, the longest name for the unused
argument is in the last position of mNames.
This is an API change that may affect programs trying to match the
specific "No value provided" message. The new error message appends the
argument that caused the error.
A solution which works with both versions is to look for "No value
provided" at the beginning of the error message.
- if (err.what() == "No value provided")
+ if (std:string(err.what()).rfind("No value provided", 0) == 0)

These test the API shown in README.md, rather than the Argument::get
function that does most of the work.
