[entries] Prefix the properties in the descriptions with (Node), (Edge) or (Graph) bc3dbbd
The lists of properties at the end of the descriptions marked edge properties with "Edge" but left node properties unmarked, or grouped them in "Nodes: `a`, ...; `b`, ..." items, so the kind of a property was often unclear. Every item now starts with (Node), (Edge) or (Graph), followed by the property names, a colon and the explanation, one item per property or group of properties; qualifications (kinds of nodes, networks) follow the names in parentheses. Properties that were only named got a short explanation, and a few items that named the wrong kind of property were corrected.

Unneeded "global files" statements, unused imports and variables, f-strings without placeholders, duplicate keys in foodweb_little_rock (keeping the order and the values used), and the second definition of get_lines() in twitter_higgs. Nothing changes in the networks or descriptions. Changed: none

+description = """A network of payment transactions between Bitcoin addresses, spanning January 2009 to April 2013. The data were derived from the public Bitcoin blockchain in the Bitcoin Transaction Network Dataset published in 2013 by I. Brugere, and comprise over 37 million transactions between public-key "addresses". They were aggregated into a network by M. Fire and C. Guestrin for their study of the evolution of network stars. Nodes are addresses (identified only by numeric identifiers), and a directed edge points from one address to another if at least one payment was made from the first to the second; multiple transactions between the same pair of addresses are aggregated into a single edge.
