  * This app creates a new Resource Stream called Intel Harvest with// GUID "{EE1C9F46-0542-4A7E-4C6A-55E2C4689419}"//.
  * You can just listen to the resorces on this stream and write code to do something with them. See 'intel_print.lua' which just prints them to the terminal.

===== 1. Installing =====

===== 2. Saving to backend Database =====

  * By default ,the App stores the harvested candidate IOC to the backend Hub database. This can take up significant disk space on busy networks. 
  * To prevent saving this stream, create a config file at ///usr/local/var/lib/trisulprobe0/domain0/probe0/contextX/config/trisulnsm_ioc-harvestor.lua// and enter the following,

<code>
return {
	SaveHarvestedItems=false,
} 
</code>
