Notes for Bubble Generator: Version 9

1. Added gas_concentration to struct Fluid, set up m_Pram [ GAS_CON ] as 0.15, the same in the form, initialize it in the function FluidSystem::AddPoint and AddPointReuse
2. Added an 1D array containing all the grids by the size of 1 in the container in the class FluidSystem, initialize it by the end of FluidSystem::AddVolume.
3. Added an bubble generator to the bottom of the container, controlled by two parameters:  GAS_LOSS(26) and BUB_GAS(27)
4. Resumed the Emit function back to the original status.
5. Changed MAX_PARAM to 30

Things to do:

1. Expanded the bottom to all of the boundaries
2. Implement the formula (8)
