Leakage Value: Limiting Display to Particles Inside or Outside the Bag

Leakage Value: limiting display to particles inside or outside the bag

Once "alive" particles will have one of the following leakage values:

0. Inside the bag
1. Escaped due to fabric porosity
2. Escaped through a vent hole
3. MPP error

Display may be restricted to any permutation of these. (By default all are shown.)
