Description:	Penalty for violating the recycling constraint.

Gas Pipeline Recycle Penalty is the penalty for violating the intrinsic recycling constraint created when Gas Pipeline End Effects Method = "Recycle". The recycling constraint is of the form:

End Volume _t = Initial Volume₁

where:

End Volume_t is the 'recycle period', which is selected as the closest period to the opposite end of the day from the start of the simulation step. For example in a simulation with daily steps where Day Beginning = "6:00 AM", Periods per Day = 48 and the step size is 30 hours, t = 48 since this would be 5:30 AM, the interval immediately before the start of the next day.

The default value of -1 means "hard constraint" i.e. no violations are allowed. A value of zero means the recycling constraint can be violated at no cost.
