Splunk Analytic Story Execution (ASX) App

This application allows you to execute and schedule [Splunk's Analytic Stories](https://github.com/splunk/security-content). Instead of running each search individually, analysts can use this app to execute and preview the results of executing or scheduling an Analytic Story end-to-end in their environments. The results of the Analytic Stories are stored in the `index=asx`, which are used to popualte the Home dashboard. Furthermore, Analytic Story Execution is capable of updating its Analytic Stories from the [security content api](https://docs.splunkresearch.com/?version=latest).
