This function performs a tree extraction by specifying node paths. The resulting tree will be stored in the ExtractedGatingTreeObject slot
of the FlowObject.
Value
The updated FlowObject with a new slot Gating$ExtractedGatingTreeObject
  containing the final, pruned gating tree.

Examples
if (FALSE) { # \dontrun{
# Assume 'x' is a FlowObject that has been processed with GatingTreeToDF and PruneGatingTree:
x <- ExtractGatingTree(x, node_paths = c("CD4.logdata.pos_CD8.logdata.neg",
"CD4.logdata.pos_CD19.logdata.pos"))
} # }
