Sort Definition
Many API endpoints support filtering and sorting of the data they return.
These endpoints usually, but not always, have a 'Search' word in their URI, like '/Consumers/Search'.
Building sort expression
Sort expressions are defined as JSON. It's defined as a collection of sort specs, for example:
Sort Expression
[ { "Column":"Column1", "Direction":"ASC" }, { "Column":"Column2", "Direction":"DESC" } ]
ASC - sort in ascending order - the default if no direction is specified
DESC - sort in descending order.
