Custom Ranges

[mattevans]

This introduces custom ranges.

An example:

query := &Query{
		Metrics: []Metric{
			{Type: "count", Field: "salary"},
		},
		Bucket: &Bucket{
			Field: &Field{
				Name: "location",
				Type: "string",
			},
			Sort: &SortOptions{
				Type: "alphabetical",
			},
			Bucket: &Bucket{
				Field: &Field{
					Name: "salary",
					Type: "number",
				},
				RangeOptions: &RangeBucketOptions{
					Period: []interface{}{
						20000,
						50000,
						100000,
						150000,
						200000,
						300000,
					},
				},
				Sort: &SortOptions{
					Type: "numerical",
					Desc: false,
				},
			},
		},
	}

As part of this, I've also added a numerical sorter, which helps in returning the custom range results in desired order.

Sweet, just an FYI I've got some other contract work that I'm trying to get finished - probably done tonight, then I'll be on this stuff and the worker stuff 👌 .
