GetGroups() private static method

Returns a list of groups of which the user is a member. It does so in a fashion that may seem strange since one can call UserPrincipal.GetGroups, but seems to be much faster in my tests.
private static GetGroups ( System.DirectoryServices.AccountManagement.UserPrincipal user ) : List
user System.DirectoryServices.AccountManagement.UserPrincipal
return List
