ericnystrom/sheptools: sheptools v1.1

Version 1.1 of sheptools provides tools to work with Shepards reports and opinion texts downloaded from Lexis-Nexis Academic. This includes transforming the downloaded HTML into tabular data and manipulating that data. Note, Lexis-Nexis has deprecated the "Lexis-Nexis Academic" web interface in favor of a different interface not compatible with this version of sheptools. These tools will continue to work on previously-downloaded files.
