    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 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:
