Easing option is not available if to install slideoutjs through yarn(npm)

[devellopah]

Have discovered if to install through yarn(npm) doing yarn install slideout the easing option not exist instead i used fx and it worked. Never saw this fx option before, so if it substitution for easing option please update readme file, if it were a predecessor of easing option and had been deprecated in favor of it looks like you'd better update npm package.

p.s. have spent two hours to spot an issue, please react to this.
