	* wind profiles with flag readwinds=1 (uses the whole file)

2018-01-04 2.2.1 Giovanni Macedonio <giovanni.macedonio@ingv.it>
	* Added settling velocity model of Pfeiffer et al., 2005.
	* Corrected model of Dioguardi et al., 2017 at low Reynolds numbers.
	* The thickness of the vertical layers (hlayer) is read from the
	* input file.
	* The name of the configuration file is read from the command line.
	* New optional block FILES added in the configuration file.

2017-05-30 2.2 Giovanni Macedonio <giovanni.macedonio@ingv.it>
