    This function initiliazes the variables required for running
B{fastestmirror}
    module. The variables are initiliazed from the main section of the
plugin file.

    There are no parameteres for this function. It uses global variables to
    communicate with other functions.

    This function refers:
        - L{get_hostfile_age}

    @param verbose : Verbosity of output.
    @type verbose : Boolean
    @param socket_timeout : The default timeout for a socket connection.
    @type socket_timeout : Integer
    @param hostfilepath : Absolute path to the plugin's cache file.
    @type hostfilepath : String
    @param maxhostfileage : Maximum age of the plugin's cache file.
    @type maxhostfileage : Integer
    @param loadcache : Fastest Mirrors to be loaded from plugin's
cache or not.

    This function is called after Yum has initiliazed all the repository
information.

    If cache file exists, this function will load the mirror speeds from
the file,
    else it will determine the fastest mirrors afresh and write them back
to the cache
    file.

    There are no parameteres for this function. It uses global variables to
    communicate with other functions.

    This function refers:
        - L{read_timedhosts()}
