## Description

The query extension adds a query method which allows a different way to construct queries instead of the usual method chaining:

    dataset = DB[:items].query do
      select :x, :y, :z
      filter{(x > 1) & (y > 2)}
      reverse :z
    end

You can load this extension into specific datasets:

    ds = DB[:table]
    ds = ds.extension(:query)

Or you can load it into all of a database's datasets, which is probably the desired behavior if you are using this extension:

    DB.extension(:query)
