/**
 * Deals with client configuration and preferences.
 *
 * DMDirc's configuration system is based upon a set of 'identities'. Each identity has a specific
 * target which controls which elements of the client it is applied to. Identities can be targeted
 * to the client as a whole, and individual networks, servers or channels. Identities may also
 * specify an order, which controls in which order they are checked when looking up a configuration
 * setting.
 *
 * Most of the time configuration settings need to be sourced from multiple identities. For example,
 * channel settings will come from the channel's identities if any exist and if any contain the
 * setting in question. Failing that, they will come from the server's identities, then the
 * network's, and finally the global identities. This ordering and lookup behaviour is captured in
 * the {@link ConfigManager} class, which can determine which identities should be used in a
 * specific context and then use those to look up settings appropriately.
 *
 * Identities are all stored on disk under the 'identities' directory in the user's DMDirc profile.
 * Default identities in this package are extracted automatically by the {@link IdentityManager} if
 * they do not exist. Identities use the DMDirc {@link com.dmdirc.util.io.ConfigFile} file format.
