[math] Add sign() method to MathUtils

           Summary: [math] Add sign() method to MathUtils
           Product: Commons
           Version: Nightly Builds
          Platform: All
        OS/Version: All
            Status: NEW
          Severity: Normal
          Priority: Other
         Component: Sandbox
        AssignedTo: commons-dev@jakarta.apache.org
        ReportedBy: HotFusionMan@Yahoo.com


While implementing Ridders' method for root finding, I encountered a need for a
function that would return +1 or -1 depending on the sign of its argument.  I
started a MathUtility class to hold such things, but Phil beat me to the punch
by submitting MathUtils, so I am submitting additions to his class.
