• Part 1: Fixed warning when working with a vector of filenames as argument to datadir.
• Part 2: Added argument max_calendar_days to allow user to control the maximum number of calendar days to include in analysis, irrespective of argument strategy value.
• Part 2: Argument maxdur is no longer specific to strategy 1, but applied irrespective of value of argument strategy.
• Part 4: Fixed issue that sleeplog is indicated as the guider even when when corresponding timestamp cannot resolve to timestamp.
• Part 5: Time series output filenames now auto-stripped from [.]|rdata|csv|cwa|gt3x|bin character string.
• Fixed issues introduced in 2.5-6 release: maxNcores was not defined in part 1, params_output and not passed on to part 3, and params objects were unneccesarily repeatedly checked.
