/* A class representing a single private message. Each message belongs to a
user.

Each message has a sender, a recipient, a date, a boolean variable indicating
whether it is read or not, a subject, a message and a message id.

The object is constructed from a string in the following format:
sender~recipient~date~isRead~subject~message~messageId

Each message is a line in a file in db/PMs based on the recipient's username:
db/PMs/<username>.dat
