[Feature] Sorting and ordering results

[jspeis]

For Data USA:

• [x] Ability to choose a Measure on which the data will be sorted
• [x] Ability to specify sort order (e.g. descending / ascending)

This will be helpful for querying results by Metric in Descending order, for example

@jspeis do we need to sort on multiple "columns"? If so, how would you specify that behavior?

[jspeis]

Multiple columns not required. Could be cool if easy to do, otherwise no worries

Also, do we need to support sorting by the members of a dimension? (e.g. Counties in alphabetical order)

[jspeis]

yes
