This class maintains a list of open files and a list of closed log files. We

can't simply leave all files open because we'll run out of file
|
|
descriptors.
|
|
|
|
The "run" method of this class will cycle between doing several things:
|
|
1. First, it will check if any new files have appeared in the log
|
|
directory. If so, they will be added to the list of closed files.
|
|
2. Then, if we are unable to open any new files, we will close all of the
|
|
files.
|
|
3. Then, we will open as many closed files as we can that may have new
|
|
lines (judged by an increase in file size since the last time the file
|
|
was opened).
|
|
4. Then we will loop through the open files and see if there are any new
|
|
lines in the file. If so, we will publish them to Ray pubsub.
