/// Parse and store program command-line arguments for use by other ARIA classes.
/**
This class is made for parsing arguments from the argv and argc variables
passed into a program's main() function by the operating system, from
an ArArgumentBuilder object, or just from a string (e.g. provided by WinMain()
in a Windows MFC program.)
It will also load default argument values if you call
loadDefaultArguments(). Aria::init() adds the file /etc/Aria.args and the
environment variable ARIAARGS as locations for argument defaults, so
loadDefaultArguments() will always search those. You can
use this mechanism to avoid needing to always supply command line parameters
to all programs. For example, if you use different serial ports than the defaults
for the robot and laser, you can put a -robotPort or -laserPort argument in
/etc/Aria.args for all programs that call loadDefaultArguments() to use.
You can add other files or environment variables
to the list of default argument locations with
addDefaultArgumentFile() and addDefaultArgumentEnv().
Note that the wasReallySet behavior has changed. It used to set
the variable to false or to true, now it will only set it to false
if 'setWasReallySetOnlyTrue' is set to false. By default that is
set to false, but you can just set it to true after you make the
parser with no ill effects since all of the built in Aria parsers
will play nicely with this value, setting it to true or false while
they parse but then setting it to whatever it was when they
started. This change in behavior is so that checking for two
things (like -robotPort and -rp) can work without a lot of extra
work.
