update node metadata to include the stage of development

[kwhitehall]

As a part of the node metadata is would be useful to determine the stage of development of the MCS the node represents.
This issue depends on #190 metadata being available as well.

@kwhitehall What are the different stages that should be represented ? Could you list them so we can find out where can we make edits in the code.

Hi @sujen1412 the stages to be represented are initialization, mature, and dissipation. They are defined according to the area and the brightness temperature. You need to have a subgraph first inorder to determine the stage of the node. In terms of edits in the code, this will require updating the nodemap, after traversing the subgraph and determining the relationship of the area and temp of consecutive nodes. I'm currently working on this... sorry should have assigned.

[EDIT]
Right now
The actual code to traverse the graph and determine the stage is going into MCSOps
The updating the nodeMap in MCSNode
Some functionality may be added to MCSUtils
