= Analysis =

== Overview ==
This task involves the improvement of org.sophie2.core module.

== Task requirements ==
 * Revise org.sophie2.core and add some extra functionality that is needed:
  * Provide a @Lazy annotation for AutoProperties:
   * currently the compute() method is invoked on creation of the AutoProperty
   * @Lazy should be used to implement lazy invocation of the compute() method in the AutoProperty, which means the method will be called on demand
   * this would provide a performance optimization of AutoProperties holding references to objects which potentially will be never used - for instance some GUI object like an "Advanced settings" panel, which the majority of users wouldn't use at all or would use quite seldom
  * Provide a @Const annotation for AutoProperties:
   * @Const must ensure that the compute() method is called only once
 * Write appropriate unit tests 

== Task result ==
The result of this task should be source code (including unit tests). 

== Implementation idea ==
Use reflection for @Const.
