/*
 Dependency injection

 Wrap any function with an additional first parameter of appContext which can be easily
 destructured.

 For example: when a function takes a single parameter foo but that function also needs to
 use the Meteor service and Bar collection it can be constructed as so:

 const func = ({ Meteor, Bar }, foo) => {
 ...function here...
 })

 export default inject(func)

 The exported function can then be called (passing 1234 as foo) as follows:

 fooFunc(1234)

 This way most of the app becomes pure functions which are easier to understand and test.
