Arguments

x	ncdf4 object
var	variable id (name)
index	named list of [start,length] vectors for each dimension lonsuch as c(1,913) latsuch as c(1,443) timesuch as c(5, 7) which starts on the 5th and ends on the 12th levsuch as c(8,1) which retrieves just the 8th level
collapse_degen	logical, if FALSE then preserve length 1 dimensions NAM218 grib files have variables with either [lon, lat, time] or [lon, lat, lev, time] dimensions. If the grib files stored those in [lon, lat, time, lev] order we could have dropped degenerate dimensions.
