/**
* A tool for Hadoop eco system that makes it easier to parse Omniture Click Stream data.
* It consists of custom input format and line reader. Works identically to TextInputFormat except for
* the fact that it uses a EscapedLineReader which gets around Omniture's pesky escaped tabs and newlines.
* For more information about format, please refer to Omniture Documentation at
* https://marketing.adobe.com/resources/help/en_US/sc/clickstream/analytics_clickstream.pdf.
