"""Local user's current options/profile information
User settings are stored in an INI-style configuration
file. This object uses the ConfigParser module to load
the settings. At the moment the only storage mechanism
is in the set_server_registered method, which loads the
file directly from disk, then dumps it back out again
immediately, rather than using the class.
The profile is also responsible for loading the user's
public and private ssh keys from disk.
Attributes:
name -- child's name
color -- XoColor for the child's icon
server -- school server with which the child is
associated
server_registered -- whether the child has registered
with the school server or not
pubkey -- public ssh key
privkey_hash -- SHA has of the child's public key
