Initial wrapper implementation.
Removed init for now.
Initial implementation of formatColumn.
Wrapped functions documented and working, sans option-setting ability.
Should now be able to set values with $.accounting('settings', settingsOject);
Should now be able to override settings when calling an individual function.  Uses the object option whenever multiple arguments could be present.
Setting the settings now no longer overwrites other settings.  This should set the jQuery wrapper to be ready to ship.
IE7 bug on defaults() caused script to fail.  Added a line to ensure that if the first argument to defaults() is null, as it is in IE7, then to reset it to an empty object.
