= Analysis =

== Overview ==
 This task requires a base implementation of the Halos. The idea is to have a base hierarchy in a separate module that the actual implementation classes use.

== Task requirements ==
 * Create a module org.sophie2.base.halos
 * Extract the base hierarchy for Halos and put it in that module. (all halos are now in the org.sophie2.main.view module).
 * Create a UML diagram for the base classes.
 * Make the org.sophie2.view.main dependable on the org.sophie2.base.scene module.
 * Review currently implemented classes of halo buttons, menus, huds.
 * Provide a general explanation of how new halos should be implemented.
  * How should one create a HUD.
  * How should one create a Halo Button.
  * How should one create a Halo Menu.

== Task result ==
 * wiki page.
 * diagrams
 * source code
 * new module in sopehie2-platform.

== Implementation idea ==
 * create the module.
 * fix the halos.
 * create other things described in Task Requirements section.

== Related ==
 * a similar things is already done by [wiki:BASE_LAYOUT_R0]
  * see org.sophie2.base.layout module and see how are things done there.
  * base halos should be done in a similar way.

== How to demo ==
 * open the corresponding wiki page given in the design or implementation section.
  * see if everything is clear.
  * diagrams
  * explanations
 * open eclipse
  * see if org.sophie2.base.halos exists
  * run the demo
  * run the tests
  * examine source code.

= Design =
 * New things:
  * A module org.sophie2.base.scene will be created.
  * module org.sophie2.main.view will depend on the former.
  * the new module will provide the base hierarchy of halos.
 * Refactored things:
  * the 
 * Diagrams:
  * Hierarchy diagram for halo buttons and huds. They both have a visual representation - the !HaloSceneElement that has a !JComponent.
