backend handles SQL
-----------------------------------

`sql = "SELECT tps.srce_set(_name, _json)"`

`json_return_value = connection.execute(sql)`

handle json_return_value
* insert: notify and clear? update list of sources on screen?
* could not insert: print reason from json

import the data
------------------------------------
SELECT
    *

    tps.srce_import('C:\users\fleet\documents\tps_etl\sample_discovercard\data.csv','DCARD') x(message)
