The following enhancement will be made:

The main goal of the enhancement is to allow users to load pre-made maps. Users
will be able to scroll through a list of descriptive map titles and select one
to view. When a map from the list is selected, the application will reset itself
to show the user the new map and legend.

o Specify contexts as a name/url pair as part of the HTML template
o New Map (at full extents as defined in the context file)
o New/modified map legend (based on the context layers)

Design Requirements

* Should be embedable on the page, in a scrolling layer or iframe
* Select from a list of maps as dropdown list (select) that displays names from
widget tag.
* support embedded or popup mode
* for embedded mode, support widgetstyle and widgetclass

This enhancement will be implemented as an enhancement to the UploadContext
widget and as a new embeddable version (ContextSelector widget) that just
displays a dropdown list.  The UploadContext enhancement will add a dropdown
list to the popup dialog box.
