def user_cache_dir(appname):

    Return full path to the user-specific cache dir for this application.

        "appname" is the name of application.

    Typical user cache directories are:
        Mac OS X:   ~/Library/Caches/<AppName>
        Unix:       ~/.cache/<AppName> (XDG default)
        Windows:      C:\Users\<username>\AppData\Local\<AppName>\Cache

    On Windows the only suggestion in the MSDN docs is that local settings go
    in the `CSIDL_LOCAL_APPDATA` directory. This is identical to the
    non-roaming app data dir (the default returned by `user_data_dir`). Apps
    typically put cache data somewhere *under* the given dir here. Some
    examples:
        ...\Mozilla\Firefox\Profiles\<ProfileName>\Cache
        ...\Acme\SuperApp\Cache\1.0

    OPINION: This function appends "Cache" to the `CSIDL_LOCAL_APPDATA` value.
