This file specifies the format for describing allocation changes.
When the user publishes an assignment, ST Module outputs a list of
differences between the old and new assignment in this format, and
then WbE uses it to update the conference schedule on the web.

The changes include additions of new allocations, and changes and
deletions of old allocations. For additions of new allocations and
changes of old allocations, the format is as follows:

EDIT, <description>, <date>, <start>, <duration>, <room>

<description> string describing the event (e.g. "Poster Session")
<date>        new date in the SQL YYYY-MM-DD format (e.g. "2005-03-07")
<start>       new start time in the SQL HH:MM:SS format (e.g. "13:30:00")
<duration>    new duration in seconds (e.g. "3600")
<room>        string describing the new room (e.g. "WEAN 4623")

Example: EDIT, Poster Session, 2005-03-07, 13:30:00, 3600, WEAN 4623

For deletions of old allocations, the format is as follows, where
<description> is the string describing the event:

EDIT, <description>, 1970-01-01, 00:00:00, 0, grass

Example: EDIT, Poster Session, 1970-01-01, 00:00:00, 0, grass

All additions and changes should be before all deletions. Furthermore,
we should follow the standard rules of CSV files:

- A field containing commas must be enclosed in double quotes (").
- A field containing line breaks must be enclosed in double quotes.
- A field containing double quotes must be enclosed in double quotes,
  and each internal double quote must be doubled.
