Goals

• Add formal unit testing with testthat
• Move documentation over to roxygen
• Transition dependencies to imports
• Transition data to data-raw and use rda data
• Speed up the L-moments calculations (where possible)
• Make general performance improvements
• Remove pglo.R and update documentation
• Add parallel processing support
• Change default plot title to include "SPI"/"SPEI"" when appropriate
• Change default y-axis title to say "z-values"
• Allow user to change the title when plotting spi/spei
• Increase test coverage to 75%
• Increase test coverage to 90%
• Figure out how to get the accented letters back without upsetting travis-ci
