== Send vector as on_rez parameter ==


this script is to demonstrate how a vector could be sent to a rezzed object
without using the listen event, sending it throught the start parameter in
the llRezObject() function.  There are two parts, the decoder that would be
in the rezzed object to convert the start_parameter back to a vector the
other part(s) is the encoder there are two encoders one to send a float vector
eg <1.34,4.87,9.96> and one to send a integer vector eg <13,4,999>
== Limitations ==
-- using the float encoder the maximum value that can be sent is 9.99
-- using the float encoder it is only accurate to 2 decimal places
-- using the integer encoder the maximum value that can be sent is 999
-- one big limitation at the moment is that only posative values can be sent
