Many fixes plus implemented var synchronization
- Improved error handling
- Added Range difference to get missing data ranges
- Implemented variable synchronization for simple serial scenario
Next step is to introduce cache handling in VC2

Added more features in DateTimeRange to prepare variable synchronization
DateTimeRange and helpers has to ease any operation on time ranges
to allow more complex operations between variables.

Introduced opaque library from Kyle Markley and improved DateTimeRange
class
Opaque library allow safer manipulation of numeric values and gives tem
a meaning. This should help to prevent stupid mistakes. A first usage in
SciQLop is Seconds which are double but have a specific meaning, a
DateTimeRange can only be multiplied by a double (-> zoom) but only
seconds can be added to it (-> pan). Even a zoom could be an opaque type
in the future: Range/Range->Zoom, Range*Zoom->Range, Zoom*Range->Error.
DateTimeRange class has now many arithmetic operators implemented
this will allow to implement zoom/pan operations in only one place
and test them.
