Multi-faceZone based blending differencing scheme.
Schemes are set in dictionary format according to:
divSchemes
{
.
.
div(phi,U) Gauss zoneBlended
{
default defaultScheme;
faceZone1 scheme1;
faceZone2 scheme2;
...
faceZoneN schemeN;
}
.
.
}The default entry specifies the background scheme; additional schemes
can be set per faceZone, e.g. scheme1 is applied to facZone1,
scheme2 is applied to faceZone2 etc.
