El Manzano (2.7-4)

• Part 1: Arguments configtz and desiredtz now also used for .gt3x data.
• Part 1: Temporary copy of read.gt3x code replaced by direct dependency on read.gt3x
• Vignette: Cut-point documentation paragraph improved.
• Part 1: Mismatches in the reading of ActiGraph csv files handled (mainly because of header = TRUE resulted in some acceleration values disregarded as they were considered a header in each iteration).
• Part 1: Fixed issue #573 (code redundancy to impute time gaps in read.myacc.csv and g.imputeTimegaps)
• Part 1: g.imputeTimegaps extended so that now it can handle time gaps at the begining, at the end of the file, and time gaps from one chunk to the next one.
• Part 2: QC plot now with legend and minor updates to layout.
• Part 4: Person level aggregation now takes place per filename instead of per ID, which should prevent that identical IDs in repeated recordings get aggregated into a single ling.
• Part 4: ID matching between accelerometer file and sleep log improved by ignore spaces.
