""" Translates a ugly data point name (DP_351652) into something uglier (A0numeric0).

The translation will be needed while exporting old ScadaBR databases into the new main database.
For this class we will assume that:

	Data point (dp) --> somewhat like "DP_351652"
	Param 			--> somewhat like "A0numeric0"

Keep that in mind.
