== Calling Pattern ==
Call
local k = sl.linklist()
-- later
local n = k.insertbefore(a,b)

Arguments
a is a number
b is any value

Results
n is a number

== Example Usage ==

local k = sl.linklist()
local j = k.insertb(0,'one')
local j0 = j
j = k.insertb(j,'two')
j = k.insertb(j,'three')
print(k.getpos(j0))
print(k.getpos(j))

== Description ==

Calling insertbefore creates a new link with value b and inserts it before the link with psuedo-index a. If the list is empty, a can be any number and the new link is also the head and tail of the list. If the list is non-empty and a is not a valid pseudo-index, then insertbefore fails and returns 0.
