Overview

Warning: This version uses the new MeteoIO syntax, so you must update your ini files!

Details

Necessary changes to work with the latest syntax in MeteoIO (named arguments).
New documentation, hoping that which components are involved in a simulation would get clearer
Modernizing the examples, removing some old formats from the example input files

When writing out timeseries as SMET, the timezone was missing making everything appear as GMT.
A mistake has been found and fixed in Canopy.
A "bug" has been fixed in the fluxes outputs: when writing out ILWR, it was actually the ILWR as absorbed by the snowpack, ie with the snow surface emissivity effect. This has been changed and now it is a true, atmospheric ILWR.
The serialization (for MPI operation) had some very serious bugs (leading to loss of data) that got fixed
The serializations have been rewritten to have more precise types (istream, ostream) and some missing members have been added.
When computing the stability with the Relative Threshold Approach, an invalid index was used (reading one element after the last). Now the top node is receives a default stability value (0.0).

A few methods have been tagged as either const or static.
A (stupid) warning on some Clang compilers (newer osX) has been turned off.
A compiler option was not supported by some versions of gcc, it is now properly tested for the version number.
A possibly ambiguous syntax prevented compiling on new version of gcc, it has been fixed.
Several methods have been declared static/const when appropriate and several methods parameters in Canopy declared const when possible.

When declaring CANOPY=true, if a sno file would contain a CanopyDirectThroughFall of 1 with CanopyHeight=0, it would trigger an exception. This is not the case anymore, now if the LeafAreaIndex or the CanopyHeight are zero, we simply skip the Canopy module and call MicroMet instead.
In order to avoid run_SnowpackModel() to have to re-create several objects, a lot of class members in the said objects are now const, improving the run time.
the declared Canopy objects are now recycled between call, so there is no need anymore to re-construct a Meteo object in the time loop of run_Snowpack() leading to speed gains (major in the case of a distributed simulation)
Each element now has a unique (and increasing) Element ID. This ID is written out in the .pro files for layer tracking (as parameter 0504)
