mmnode-ticker: display crypto assets by market cap
Examples:
# Display top 2000 assets by market cap:
$ mmnode-ticker 2000
# Display assets 201-300 by market cap, displaying all available columns:
$ mmnode-ticker --widest 201-300
# Display asset 32 by market cap:
$ mmnode-ticker 32-32
Testing/demo:
$ test/cmdtest.py -e scripts.ticker

Overview mode displays prices of all configured assets, and optionally the
