[Discuss-gnuradio] GRC - Always Generate Functions Probes Last?

[John Malsbury]

I often find that  GRC instantiates function_probes/threads before the block/object/probe that is being called by the function probe, which causes an exception.  It takes some trickery, like copying and re-pasting blocks in GRC to change the order in the generated python file.

To fix this I've modified:

grc/core/FlowGraph.py

grc/core/generator/Generator.py

grc/core/generator/flow_graph.tmpl

so function probes are always declared after all blocks.  

Is there a reason why we haven't done this before?  If not I can submit a PR for the simple fix.
