RUNTIME: Variable trace now uses limited list and buffer instead of flags in instance tree that was requiring systematical instance tree traversal, and worst size buffer. Forcing and retain still use tree traversal.

""" Description:
EnhancedStatusBar Is A Slight Modification (Actually A Subclassing) Of wx.StatusBar.
It Allows You To Add Almost Any Widget You Like To The wx.StatusBar Of Your Main
Frame Application And Also To Layout Them Properly.
What It Can Do:
1) Almost All The Functionalities Of wx.StatusBar Are Still Present;
2) You Can Add Different Kind Of Widgets Into Every Field Of The EnhancedStatusBar;
3) The AddWidget() Methods Accepts 2 Layout Inputs:
- horizontalalignment: This Specify The Horizontal Alignment For Your Widget,
And Can Be ESB_EXACT_FIT, ESB_ALIGN_CENTER_HORIZONTAL, ESB_ALIGN_LEFT And
ESB_ALIGN_RIGHT;
- varticalalignment: This Specify The Vertical Alignment For Your Widget,
And Can Be ESB_EXACT_FIT, ESB_ALIGN_CENTER_VERTICAL, ESB_ALIGN_BOTTOM And
ESB_ALIGN_LEFT;
EnhancedStatusBar Is Freeware And Distributed Under The wxPython License.
