Mercury

Mercury is an API that provides authenticated access to event logs stored in IPFS via Orbit-DB. [TODO]

TODOS

First, install ipfs. When running the app, run the daemon with pubsub enabled
```
    ipfs daemon --enable-pubsub-experiment
```
navigate to the root directory and execute
```
    npm install
```
and then
```
    npm start
```
by default, the API will run on port 3000.
