                    boolean isCall,
                    SimpleConstantContinuousBarrier barrier)

Computes the price of a barrier option.

Parameters:

spot - the spot

strike - the strike

timeToExpiry - the time to expiry

costOfCarry - the cost of carry

rate - the interest rate

lognormalVol - the lognormal volatility

isCall - true if call, false otherwise

barrier - the barrier

Returns:

the price
