+RopeKnocking function!
+
+This creates a rope-knocking challenge.
+The player spawns with one hog and a rope and must kill all other hogs
+by rope-knocking before the time runs out.
+The player wins points for each kill and gets a time bonus for killing
+all enemies.
+
+params is a table with all the required parameters.
+Fields of the params table:
+
+	MANDATORY:
+	- map: Map name
+	- theme: Theme name
+	- turnTime: Turn time
+	- playerTeam: Player team info:
+		{
+			x, y: Start position
+			faceLeft: If true, hog faces left
+		}
+	- enemyTeams: Table of enemy team tables. each enemy team table has this format:
+		{
+			name: Team name
+			flag: Flag
+			hogs: Hogs table:
+			{
+				x, y: Position
+				faceLeft: If true, hog faces left
+				hat: Hat name
+				name: Hog name
+			}
+		}
+
+	OPTIONAL:
+	- missionName: Mission name
+	- missionType:
+		0: None/other: No special handling
+		1: Challenge: Will save mission variables at end (default)
+	- killBonus: Score for killing all hogs (one hog scores ca. (killBonus/<number of enemies)) (default: 6000)
+	- timeBonus: Maximum theoretically possible time bonus (default: 6000)
+	- gameFlags: List of game flags, if you want to set your own
+	- extraTime: Extra time awarded for each kill, in milliseconds (default: 0)
+	- valkyries: If true, play "Ride of the Valkyries" at final enemy (default: false)
+	- onGameInit: Custom onGameInit callback
+	- onGameStart: Custom onGameStart callback
+	- onVictory: Function that is called when the mission is won.
+
+	Hint: Use onGameInit and onGameStart to place custom gears and girders
+	Hint: Use onVictory to save campaign variables if using this in a campaign
