Changes in version 0.6.1                        

    o   Fixed a bug where read_events2 and read_keds2 would not accept
	a vector of filenames as read_events and read_keds do

    o   Updated documentation for the one a day filter to clarify that 
	 date, source, target, and event code determine duplicate status

    o   Updated README and added reference to data.table

                         Changes in version 0.6                         

    o   Updated the code to pass modern checks, the contact email to 
	 one that works, and the vignette to note that you can do 
	 everything here with dplyr and tidyr these days

    o   read_eventdata now checks for KEDS documentation markers and 
	 ignores these lines (provided they always come first, which 
	 they seem to empirically)

    o   An rmd vignette

    o   `as.data.frame` generic implemented sensibly for event scale objects

    o   `read_eventdata2` and `read_keds2` are slower than their counterparts but
	 more robust to line noise and pasted together KEDS output files.

                  Changes in version 0.5 (2012-01-07)                   

    o   Made read_keds a special case of read_eventdata, a general purpose 
	 event data data reading function

    o   read_keds now reads multiple output files

    o   now bundles CAMEO codes and conflict-cooperation scores

                         Changes in version 0.4                         

    o   introduced underscore functions because we like python and we now can

    o   count data output now possible with dyad function

    o   now has tests for most functions using test_that
