[in]	lfirst_tree	The local id of the first tree of that part.
[in]	num_trees	The number of trees of that part.
[in]	lfirst_ghost	The local id of the first ghost of that part.
[in]	num_ghosts	The number of ghosts of that part.
[in]	alloc	If true then the first_tree array is allocated for the number of trees and ghosts. When a cmesh is copied we do not want this, so in we pass alloc = 0 then.
