2011-03-22	Sascha L. Teichmann	<sascha.teichmann@intevation.de>

	Finished import of WSTs.

	TODO 1: Speed it up! It takes on a high end machine over 7(!)
	        minutes only for the data of the Saar.
	TODO 2: Double precision floating point representations produced
	        by the the parsers leed to unique constraint violations
			in the backend on a second run. So the import is currently
			only working on freshly initialized data bases.
			More consequent working with BigDecimal and some
			rounding may be of help here.

	* src/main/java/de/intevation/flys/model/WstColumnValue.java:
	  Added convinience constructors.

	* src/main/java/de/intevation/flys/importer/ImportWstColumnValue.java:
