Network Value to Transactions Ratio Data Collection and Visualization

**User Story**
As an `interested party` I want to `collect and display daily active use and the value of operations within the BitShares Platform` so that I may `make proper comparisons to other industry entities`.

**Impacts**

**Additional Context**
Reference Material:
[Network Value to Transactions Ratio](https://coinmetrics.io/nvt)

BitShares currently implements a plugin for Elasticsearch and Kibana may be used for visualization. The need is to extract the data in a usable format for further analysis. Scenarios include:
- Total number of active users (daily, monthly) performing various operations (transfer, order create/cancel/fill, etc.)
- Total value contained within various operations (transfer, order create/cancel/fill, etc.) in time series (daily, monthly)
- Note "value" should be based on BTS to ensure consistent aggregation and comparison
- For market pairs not containing BTS, a conversion is likely needed

Note: This is note "Core" work, but important to the community. Any solution must be provide with the MIT license.

## CORE TEAM TASK LIST
- [ ] Evaluate / Prioritize Feature Request
- [ ] Refine User Stories / Requirements
- [ ] Define Test Cases
- [ ] Design / Develop Solution
- [ ] Perform QA/Testing
- [ ] Update Documentation

Start by reviewing BitShares' existing Elasticsearch plugin and the referenced Network Value to Transactions Ratio material. Clarify the user stories, requirements, and test cases for daily/monthly active users and BTS-denominated operation values before designing the data flow and visualization. Done means the data is extracted in a usable format, validated, visualized, tested, and documented under the MIT license.
