Here's a two-part inquiry.
1) Although I appreciate the benefits of ClientBundle for styling purposes like minification and obfuscation, is there an alternate method to style a CellTable without relying on generated CSS class names? Can these class names be overridden directly through a reference in the index.html file to a CSS file with the appropriate classes, bypassing the use of ClientBundle?
2) If opting for the ClientBundle approach, it appears that the CSS file replacing default GWT styles needs to be referenced in a specific manner within the code. Is there a way to refer to a CSS file located outside the package where the interface is defined, perhaps in a different source directory than the project's base src directory?
