/**
 * Tests amount of time taken to invoke Class methods
 *
 * The expected results are as follows:
 *   - Method invocations are expected to be slower than invoking a method on a
 *     conventional constructor instance. This is because of the method wrapper
 *     used by ease.js.
 *   - Public methods externally should be invoked very quickly. They are part
 *     of the class's prototype and therefore easily accessible.
 *   - Public methods /internally/ are likely to be invoked slightly more
 *     slowly. This is because it takes one extra step down the prototype chain
 *     to access them. The difference should be minute.
 *   - Protected and private methods internally should be accessed fairly
 *     quickly since, like public methods externally, they are first on the
 *     prototype chain.
 *     - Protected members will be accessed more slowly than private members,
 *       because they are one step lower on the prototype chain. Future versions
 *       will remove this performance hit if the Class contains no private
 *       members.
