The parcel initial velocity can now be set using the new `velocityType`
entry, taking one of the following options:

- fixedValue   : (default) same as earlier versions, requires U0
- patchValue   : velocity set to seed patch face value
- zeroGradient : velocity set to seed patch face adjacent cell value

Example usage:

        model1
        {
            type            patchInjection;
            massTotal       1;
            SOI             0;
            parcelBasisType mass;
            patch           cylinder;
            duration        10;
            parcelsPerSecond 100;
            velocityType    patchValue;
            //velocityType    zeroGradient;
            //U0              (-10 0 0);
            flowRateProfile constant 1;
            sizeDistribution
            {
                type        normal;
                normalDistribution
                {
                    expectation 1e-3;
                    variance 1e-4;
                    minValue 1e-5;
                    maxValue 2e-3;
                }
            }
        }
