+ESS Supercycle Tables

+
+# Specification
+* Operating frequency: one linac cycle (14 Hz).
+* Sequential row execution.
+
+# Design Guide
+* Place a supecycle table in this directory.
+* Use "libreoffice" or "Microsoft Excel" to create/edit .csv files (comma-separated values).
+* Each table should have a unique name (name).csv.
+* Fist "row" defines keys for each dataset within its collumn (key).
