random

Creates a random knot using one of several methods:

1) Uniform random knots --- coordinates for vertices are selected uniformly at
random within a specified range (defaults are provided).  Usage is

random uniform <<optional parameters>>

the number of optional parameters is either 0, 1, 2, 3, 6 or 7

random uniform 
creates a knot with default number of beads and coordinates in the range (-10, 10)
default number of beads is current value of N-torus

random uniform N
creates a knot with N vertices and coordinates in the range (-10, 10)

random uniform N R
creates a knot with N vertices and coordinates in the range (-R, R)

random uniform N MIN MAX
creates a knot with N vertices and coordinates in the range (MIN, MAX)

random uniform XMIN XMAX YMIN YMAX ZMIN ZMAX
similar to above, but ranges for x, y and z are different.  number of beads is 
set to current value of N-torus

random uniform N XMIN XMAX YMIN YMAX ZMIN ZMAX
similar to above, but ranges for x, y and z are different and number of beads is N.

NOTE: In the above, `random uniform' may be abbreviated to `rand unif'. Also, it's
easiest to see what's going on if you click on `beads & cyls' on Main control panel first.
