Log files can be written to, closed. Their size is the number of
bytes written to them. Everything that was written to them can
be read, even if the writing happened on separate occasions,
and even if the log file was closed in between.

Various tests for log readers.
First of all, log readers can get logs by number and read what
was written to those log files. Getting nonexistent log files
raises C{ValueError}. Using anything other than an integer
index raises C{TypeError}. As logs get older, their log
numbers increase.

Test that L{DailyLogFile.toDate} returns today's date by default.
By mocking L{time.localtime}, we ensure that L{DailyLogFile.toDate}
returns the first 3 values of L{time.localtime} which is the current
date.
Note that we don't compare the *real* result of L{DailyLogFile.toDate}
to the *real* current date, as there's a slight possibility that the
date changes between the 2 function calls.
