Overview

Parses an array of decoded query params

This parser/encoder uses an already decoded array of sort strings parsed by a URI library.

Parsing:

params = ['phone_desc', 'name_asc']
set = Sorted::ParamsQuery.parse(params)
set.to_a #=> [['phone', 'desc'], ['name', asc']]

Encoding:

Sorted::ParamsQuery.encode(set) #=> ['phone_desc', 'name_asc']
