* Update mock data to reflect latest API format
* Update Table component to create a TableCard, TableSummary, and plain Table
Use the TableCard container to display mocked revenue data
* Add horizontal scroll only on the table itself
* Remove `sortable` prop, base column sortability on whether the `value` is true/false
Checking against a strict false should prevent any real 0 or ‘’ values from triggering unsortability
* Add a checkbox to the demo table
* Update accepted props
* Update README for TableCard, Table, and TableSummary
* Update README
* Fix confused defaults
