DO NOT MERGE: Adding flows and amending UI to handle different calm types to view

[LeighFinegold]

Summarising evening play with calm-hub

• Added a little README.md for running up mongo locally.
• Fairly easy to extend to host flows.
• Added traderx in initmongo script
• Change UI so that it supports all forms of calm-types

• Main feedback to @jpgough is around using integer counters to represent whole store globally or not. (The counter left in DB is not correct given init-mongo script)
• Whether any plan to validate the json document been created along the schema
• If there are no patterns or flows for a given namespace, the backend gives NullPointer but has no impact to UI
• What is the difference between the uniqueId in the calm doc vs the unique id given by calmhub?

Not saying one needs to use mongo:4.0.

I have an old mac and 4.2 didn't work :D

I think if I was to play around a bit more with the swagger api, I probably will not be able to add documents because this init mongo script adds more documents then the initial sequence number.
