Loading bar for graph generation

[KerwinSun]

Load scales exponentially with size of graph due to sorting algorithm used, large graphs take long to generate after cloned, could do with a loading bar to indicate graph is being generated.
(separate from clone loading bar)
Implementation ideas: use count for when graph is sorting, other operation run times are negligible, bind count to loading bar

Approved and can confirm that large graphs take quite some time to load on my end too

If the load truly does scale exponentially then we need to get on that because that will be a major slow down, and the algorithms involved should not be going further than n^3
