how to use predictPattern function

[monomy001]

Hi, first of all, great library! appreciate everyone's hard work.
I have a question.. How do you use the predictPattern function?
It looks as if the function is turned off deliberately.

I am hoping to be able to do something like this
var twoDayBullishInput = {
open: [23.25, 15.36],
high: [25.10, 30.87],
close: [21.44, 27.89],
low: [20.82, 14.93],
}
console.log(ti.predictPattern(twoDayBullishInput));

and it would log out an array of say
['doji','shootingstar'] of whatever OHLC values passed into the function.

would appreciate any pointers, thank you.
