Combine Float fields in a single "Vector" like field to reduce Read / write overhead of multiples grids.

[ZephirFXEC]

Enhancement

Create a custom grid type that takes N-Float grid and Convert it in a single Vector Grid of N-Dimmensions.
Use that grid to advect / read / write would reduce by N times the read and write time.

How ?

For example 3 Float grids such as Density / Temperature and Fuel could be converted to a single Vector Grid containing float data of each grids in each dimensions.
Generalisation should be possible via extensive template usage to allow for N-Dimensional Vector grids.
