+Abstract
+========
+Increased use of the RecordTimeSeries functionality within Cyclus
+has caused an increase in the number of tables in a cyclus output
+file. While this has yet to impact performance, it is conceivable 
+that it could become problematic in the future. To combat this
+a new cyclus control input field will be added to allow users to
+choose which RecordTimeSeries tables to be added to the output. 
+
+
+Motivation
+==========
+The addition of the TimeSeriesListeners added to support the d3ploy 
+archetypes caused an increase in the amount of tables being output
+by Cyclus. This change is largely user agnostic however, it can 
+cause an increased storage space for each run. As this data is unused
+by any simulation not using the listeners, it is just wasted hard disk
+space. This charge will be used to mitigate this problem. It will also
+allow uses to run a simulation that outputs only the specific tables
+they wish to see in their outputs. 
+
+
+Specification \& Implementation
+===============================
+This charge will add a field to the simulation control that will allow
+the user to specify which tables they wish to see. By default this value
+will be set to all tables, but if user wishes to specify the tables they
+wish to see they will do so by entering the string of each table's name;
+Similar to a vector input to a cyclus module. The user will also be 
+able to turn off all RecordTimeSeries tables. 
+
+
+Backwards Compatibility
+=======================
+By setting the default value of this field to be all tables it should
+be fully backwards compatible.
