docs: Invoked directly after instantiation to allow the configured component to perform
  one time initialization.  Components are expected to fail loudly if they are not
  going to be in a valid state after initialization.
  
  @param configuration the Configuration object being used by Stripes
  @throws Exception should be thrown if the component cannot be configured well enough to use.
