Minimizing imports

[sebhewelt]

I don't know whether the information in README was updated recently, or at least after ECMAScript 2015, nevertheless, I have problems with importing just as many files as I need and no more. Maybe someone will be able to help.

Currently I use these methods:

Date.today().toString("d/M/yyyy"),
     Date.today().getWeek(),
    Date.today().toString("MMM"),
   Date.today().toString("yyyy"),

Following the 'list of precedence', i though that my imports should be like this:

//culture info file
import "datejs/src/i18n/en-GB.js"; 
//core files 
import "datejs/src/core/core-prototypes.js";
import "datejs/src/core/core.js";

It didn't work. And there are more files then those listed. Later I tried adding more modules, but ended up loading almost all of them. I wonder what combination of modules would make it work.

Any help?
Thank you!
