Code does not match between GitHub and NPM

[First-unknow]

Hi, I found this.$bigHeadsExtras is not a function the error and I see in the commit you have already solved this problem.

but I found this code in node_modules

var extras = this.$bigHeadsExtras() 

but this code does not match in code in this repo that solves this problem

P.S. I already install the last version from npm (vue-bigheads@0.2.1)
https://www.npmjs.com/package/vue-bigheads
