Detailed Description

This class handles printing the history page for an article.

In order to be efficient, it uses timestamps rather than offsets for paging, to avoid costly LIMIT,offset queries.

Construct it by passing in an Article, and call $h->history() to print the history.

Subclasses must override this method to return true if the operation they will perform is not "safe" per RFC 7231 section 4.2.1. A subclass's operation is "safe" if it is essentially read-only, i.e. the client does not request nor expect any state change that would be observable in the responses to future requests.

Implementations of this method must always return the same value, regardless of the parameters passed to the constructor or system state.

When handling GET/HEAD requests, subclasses should only perform "safe" operations. Note that subclasses handling POST requests might still implement "safe" operations, particularly in the case where large input parameters are required.
