grid - group of resizable windows.
A rectangular collection of windows with shared (collapsed) borders that resize the windows to either side (syncronized shrink/expand) when moused upon.

Drag and drop an interior border to resize the windows on either side.
Double-click an interior border to enter Resize Mode: * scroll-wheel and arrow-keys move the border, and * click anywhere, Enter and Esc to exit Resize Mode.
Grids also provide a wrapper around curses.newwin that takes positioning
parameters that describe the spatial-relationship to other windows on the
screen, instead of (y,x) coordinates:

For example, this 3x13 grid with three 3x5 boxes may be described three different ways:
+---+---+---+
| a | b | c |
+---+---+---+
grid = Grid(curses.newwin(3, 13))
1) a = grid.box('a', 3, 5)
b = grid.box('b', 3, 5, left2r=a)
c = grid.box('c', 3, 5, left2r=b)
2) c = grid.box('c', 3, 5, right=grid)
b = grid.box('b', 3, 5, right=c)
a = grid.box('a', 3, 5, right=b)
3) a = grid.box('a', 3, 5, left=grid)
c = grid.box('c', 3, 5, right=grid)
b = grid.box('b', 3, 0, left2r=a, right=c)
If two endpoints are given (such as 3b), the length will be calculated to fill the gap between the endpoints.
