Reduce example

Here's an implementation for reducing a collection, using the alediaferia/go-collections package, to find the maximum value:

numbers := []interface{}{
    1,
    5,
    3,
    2,
}
collection := collections.NewFromSlice(numbers)
min  := collection.Reduce(0, func(a, b interface{}) interface{} {
    if a > b { return a } else { return b }
})
