/*
Explorer backend service
Serves precompiled angular website from the ./dist folder or any other configured folder.
This must be run from the same folder as ./dist, unless run in -api-only mode or another precompiled files folder is configured.
Environment options:
* EXPLORER_HOST - The addr:port to bind the explorer to. Do not include a scheme. Defaults to 127.0.0.1:8001
* SKYCOIN_ADDR - The skycoin node's address. You must include a scheme. Defaults to http://127.0.0.1:6420
CLI Options:
* run with "-h" as argument to see the CLI params.
Run the explorer and navigate to http://127.0.0.1:8001/api.html for API documentation.
