// Use this class as a member in your test class to set variation params for
// your tests. You can directly set the parameters in the constructor (if they
// are used by other members upon construction). You can change them later
// arbitrarily many times using the SetVariationParams function. Internally, it
// creates a FieldTrialList as a member. It works well for multiple tests of a
// given test class, as it clears the parameters when this class is destructed.
// Note that it clears all parameters (not just those registered here).
