FULL NAME:	NetCDF-4 C++ extensions

DESCRIPTION:	NetCDF-4 common functions between ncpp and aeros. Methods
		to retrieve netCDF attributes of various data types. These
		will trap any exceptions that the netCDF API throws.

		@param var the variable to get the attribute from
		@param target the attribute name to get
		@param output the variable to place the attribute, this is the return data
		@param defaultValue is the value to use if the attribute does not exist
		@returns true/false as to success of reading attribute (i.e. did it exist)
