- can use 'XX.empty()' instead of 'XX.size() == 0', 'XX.size() < 1' or
'XX.size() <= 0' or for simpler coding.
It also has the same number of characters as '!XX.size()' and /might/ be
more readable
- many size checking had 'XX.size() > 0', 'XX.size() != 0', or 'XX.size() >= 1'
when a simple 'XX.size()' suffices
- the improved side-effect of enabling -zeroTimea alters default selection
behaviour and -latestTime selection behaviour for utilities in which
accidentally using the 0/ directory can cause damage (eg, reconstructPar)
- can combine -time ranges and -latestTime
- handle new cloud locations, got missed before the release
- handle multiple clouds
- more efficient checking of fields etc.
- write case file at the end, thus we can potentially
do something more intelligent about the time set handling
