Improve upon Admin Tool Algorithms

[dyiop]

There are a few additonal features in the Admin Tool, which would potentially make it slow for larger graphs. This will be an ongoing process but to start, I can see these fixes to make:

• getting children for grid view (inUpdateGridNodes)
  • cache children of node?
    • build local copy of graph heiracrhly
      • add limit later - we could have millions of nodes.
    • issue will be when something updates
      • for now just rest all of cache but soon you could find a way to only reset the effected nodes
• getActiveNodes currently O(n^2)
  • Traverse through all nodes from an active PC. Return visited nodes
• whole Active PC’s thing
  • Is this feature necessary. It is adding significant complications to various parts of the code base.
  • It will also be an issue when we modularize core and admin tool functionality, since the “active pc” logic is currently in the core library wrapper
• to full json?
  • can we just regular function with algorithm to retreive only parents?
