== Calling Pattern ==
Call
local m = sl.machine(a[,b])
-- later
local r = m.initiate([d[,...]])
Args
d1..dN optional are variadic arguments of any type
Results
r0..rN are values returned by the a.exit function

== Example Usage ==

local s = {
initiate = function(h,...) local a = {...} print('initiating '..a[1]) return 'a' end,
a = function(h) print('a') return 'b' end,
b = function(h) print('b') return 'c' end,
c = function(h) print('c') return 'exit' end,
exit = function(h) print('exiting') return 999 end,
monitor = function(s,h,n,g) if g=='exit' then h[1]=h[1]+1; if h[1]<3 then g='a' end end; return g end,
}

local h = {0}
local m = sl.machine(s,h)
local n = m.initiate('live')
print(tostring(n))

--> initiating live

== Description ==

Calling initiate begins the execution of a previously defined state machine object by calling the function associated with the 'initiate' key in the state table. If no errors are encountered during execution, initiate returns the results returned by the 'exit' state function.

== Upon Error ==

Errors occurring in any of the state functions are reported and handled according to the operant error redirection mode.
