[lmi] tasks 2007: bug 104480: input-sequence editor

Pop up alternative input-sequence editor
http://savannah.nongnu.org/support/?104480
   'Input sequences' are a 'little language' for data that vary by
   year. A $5,000 yearly loan after retirement might be entered as
   0 retirement; 5000
   in a text control. Some users don't want to master that language,
   and would prefer a pop-up dialog for each vector field like this:

   labels: value from-duration to-duration

   controls: textctrl spinctrl spinctrl

   with the 'controls' repeated for each of a variable number of
   intervals. Alternatively, the 'controls' might be cells in a
   grid control. The 'values' might be a floating-point number,
   a constrained list of strings, or both: for example, a premium
   field must accept 'minimum' as well as '12345.67'. Similarly,
   a 'duration' could be an integer or a string like 'retirement'.

Please correct me if i'm wrong: this task is about designing and
coding a standalone widget for editing 'input sequence' expressions.
It should be an extended wxTextCtrl which allows ( to click on some
additional little button near its text area, which will open a dialog
box for) editing input sequence using a grid or a sequence of control
groups.

Plus an Xrc handler should be provided to be able to integrate this
widget into existing dialogs via xml-resources.
