docs: Tests if a named class is available from another class.
  If a class is considered available, a call to
  {@code Class.forName(pClassName, true, pFromClass.getClassLoader())}
  will not result in an exception.
  
  @param pClassName the class name to test
  @param pFromClass the class to test from
  @return {@code true} if available
