usage:

do this before using package element, eg: if you let your user to send 500 SMS per month:

create the package:

  Package.createPackage('SMS-Package','monthly',true).then(function(package){ 
    //do something here 
  });

then register the package for the user:

  Package.registerPackage(package.id,500,true,0).then(function(packageUsage){ 
    //this will return a token, store the token somewhere on your app
    // because you are going to need the token from now on.
  });

then use the use method before the user sends SMS

  Package.use(token,1).then(function(usage){ 
    //it will return current package usage count
    // it will return -1 if the package reached/passed its limit
    // if it returns -1 then you won't send the SMS for that user
    // and obviously if it returns count then the user is good to go
  });

to run the test do:

$ npm install
$ npm test
