Create a CSV from history.xml outputed by ED

This will generate the CSV file needed by write configs to write the config.xml. This is a hack right now, all this information should be in the PEcAn DB.

parse.history(historyfile, outfile = "")

Arguments

historyfile	filename of history file generated by ED.
outfile	location where to write output, if no specified it will write to the console.
