com.google.gwt.safecss.shared.SafeStylesBuilder
A builder that facilitates the building up of XSS-safe CSS attribute strings from {@link SafeStyles}. It is used essentially like a {@link StringBuilder}, but access {@link SafeStyles} instead of Strings.
The accumulated XSS-safe {@link SafeStyles} can be obtained in the form of a{@link SafeStyles} via the {@link #toSafeStyles()} method.
This class is not thread-safe.
