* callbacks for set average on fft, waterfall, number sinks

# Problems
##################################################
+* msg ports dont work with virtual connections
+ * dont fix this until pmts are used?
* hier block generation
* auto generate hier library on changes
* auto clean hier library when block removed
* dont generate py files in saved flowgraph dir
* save/restore cwd
* threads dont die on exit in probe and variable sink
-* overloaded gui classes for each platform, move param input objects into overloaded
-* align param titles in paramsdialog
-* better error for blank string params
+* align param titles in properties dialog
* weird grid params misbehaving
-* params dialog needs to dynamically update for all params
- * will not update for non-enum params
- * needs to account for added or removed params
- * example with grid params need update after notebook change
-* use .strip() on the hide property so we can do away with #slurp(s) in the templates
+* gr hier blocks have more diverse IO capabilities than we allow for
