Scale Dependent Symbol Renderer

Idea created by smorgan@trpd on Apr 13, 2010
    Just like a user can create different classes of label which can be visible/invisible at defined scales, so should symbology. The symbology tab of a feature properties should have an additional column to enter a scale at which that symbol or class of feature "turns on or off" An example would be streets. At a high level zoom, most users only need to see interstates and highways, as the user zooms in further, more detail should appear without the need to have multiple layers in the map.
