     /**
30 |  |
      * The Pull Service manages the creation of application
31 |  |
      * tools that are available to all templates in a
32 |  |
      * Turbine application. By using the Pull Service you
33 |  |
      * can avoid having to make Screens to populate a
34 |  |
      * context for use in a particular template. The Pull
35 |  |
      * Service creates a set of tools, as specified in
36 |  |
      * the TR.props file.
37 |  |
      *
38 |  |
      * These tools can have global scope, request scope,
39 |  |
      * authorized or session scope (i.e. stored in user temp hashmap)
40 |  |
      * or persistent scope (i.e. stored in user perm hashmap)
41 |  |
      *
42 |  |
      * The standard way of referencing these global
43 |  |
      * tools is through the toolbox handle. This handle
44 |  |
      * is typically $toolbox, but can be specified in the
45 |  |
      * TR.props file.
46 |  |
      *
47 |  |
      * So, for example, if you had a UI Manager tool
48 |  |
      * which created a set of UI attributes from a
49 |  |
      * properties file, and one of the properties
50 |  |
      * was 'bgcolor', then you could access this
51 |  |
      * UI attribute with $ui.bgcolor. The identifier
52 |  |
      * that is given to the tool, in this case 'ui', can
53 |  |
      * be specified as well.
