1.1.1

The initial code release with the functionality to use an Rmarkdown file to produce the supply chain GHG factors for a USEEIO model.
These release corresponds to v1.1.1 of the factors. See notes below.

• Requirements and usage are described in the README.
• This release contains the same USEEIO model specifications used in the original report, which are listed in Appendix 2, with a minor change in syntax of the model naming.
• Users can select options for sector type (Commodity or Industry), GHG and output year (2010-2016), and sector level (Detail or Summary), where every unique combination of those selections corresponds with a unique USEEIO model.
• Users can select to output factors in currency units of 2010-2018 USD, all in purchaser price.
• Data quality scores are hard-coded and stored in csv for these models and appended to the factors upon generation.
• The dependent useeior is a dedicated release for the v1.1.1 factors.

v1.1 --> v1.1.1 updates in factors

• Factors (SEFs, MEFs, and combined) for Other gases are corrected from v1.1 for all models. The error was a mapping error in matching names to characterization factors.
• Factors for CO2, CH4, and N2O are unchanged for all Detail models.
• Factors for CO2, CH4, N2O, and Other gases are corrected from v1.1 for all Summary models. The error was due to incorrect IO year specification in Summary models.
