[Dsg-halla_gas] GEM distro P&I, components list, and PPT files

[Brian Eng]

Just to keep everyone in the loop, for the flow sensors all the available stock from distributors was delivered this week.

36 of the 400 sccm (out of 50) and 10 of the 750 sccm (out of 10).

I was hoping these parts would have already be available in the Component Library of Altium to speed up designing the PCB, but they aren't.
Since time isn't as much of a concern I'll look into designing a 3D part so it will look nicer when the board is rendered. The schematic and footprint portions won't take nearly as long and can be done beforehand if the need arises.
