// Name: rd_GimmePropInfo
// Version: 0.9
// 
// Description:
// This script displays a selected property's information useful for
// script authors.
// 
// Select only a single property or property group; selection of some
// properties also select the parent property group, which is fine.
// Selection of multiple properties or property groups at the same
// property depth are not allowed. However, for multiple properties or
// property groups of different depths, the deepest property or property
// group will be used.
// 
// For keyframed properties, you can browse keyframes using the Key Info
// slider.
// 
// Note: This version of the script requires After Effects CS6 
// or later. It can be used as a dockable panel by placing the 
// script in a ScriptUI Panels subfolder of the Scripts folder, 
// and then choosing this script from the Window menu.
// 
// Legal stuff:
// This script is provided "as is," without warranty of any kind, expressed
// or implied. In no event shall the author be held liable for any damages 
// arising in any way from the use of this script.
// 
// In other words, I'm just trying to share knowledge with and help out my
// fellow AE script heads, so don't blame me if my code doesn't rate. :-)
