def drawMinBoundingBox(sel="(all)", lineWidth=2.0, r=1.0, g=1.0, b=1.0):
"""
DESCRIPTION
Given sel, draw the minimum bounding box around it.
USAGE:
drawMinBoundingBox [sel, [lineWidth, [r, [g, b]]]]
PARAMETERS:
sel, the selection to enboxen. :-)
defaults to (all)
lineWidth, width of box lines
defaults to 2.0
r, red color component, valid range is [0.0, 1.0]
defaults to 1.0
g, green color component, valid range is [0.0, 1.0]
defaults to 1.0
b, blue color component, valid range is [0.0, 1.0]
defaults to 1.0
RETURNS
string, the name of the CGO box
NOTES
* This function creates a randomly named CGO box that minimally spans the protein. The
user can specify the width of the lines and also the color.
* Maybe add a padding function? This might help docking folks -- eg. add a 5 Ang border around
the protein then draw the box there?
