Helper method to obtain the mesh federation tile index.
Syntax
tSigned32 getFederationTileIndex() const;
Return Value
If this mesh was created as a mesh federation tile then the federation tile index for this mesh
is returned.
If this mesh was not created as a mesh federation tile then -1 is returned.
Remarks
Added in 5.19.
Note that tile meshes generated by SDK releases prior to 5.18 and loaded from persistence do not store a tile index
and in this case -1 will be returned.
