 /**
 25  
  * The ExecutionOptions contain a set of options that can be passed to the KRMS
 26  
  * engine to control certain aspects related to it's execution.  It supports
 27  
  * two different types of options:
 28  
  * 
 29  
  * <ol>
 30  
  *   <li>flags - a map of pre-defined boolean {@link ExecutionFlag} instances which can be either true or false</li>
 31  
  *   <li>options - a general-purpose map of Strings which can be used to define optinos that have non-boolen values</li>
 32  
  * </ol>
 33  
  * 
 34  
  * <p>The options map can be used to pass user-defined or provider-specific options.  The ExecutionOptions are made
 35  
  * available as part of the {@link ExecutionEnvironment} during engine execution.
 36  
  * 
 37  
  * <p>Instances of ExecutionOptions are not safe for use by multiple threads.
