docs: Get the URL of the passed resource using the class loader of the specified
  class only. This is a sanity wrapper around
  <code>class.getResource (sPath)</code>.
  
  @param aClass
  The class to be used. May not be <code>null</code>.
  @param sPath
  The path to be resolved. May neither be <code>null</code> nor empty.
  Internally it is ensured that the provided path does start with a
  slash.
  @return <code>null</code> if the path could not be resolved using the
  specified class loader.
