class SoSPrepper():
    """
    A prepper is a way to prepare loaded mappings with selected items within
    an sos report prior to beginning the full obfuscation routine.

This was previously handled directly within archives, however this is a bit
    cumbersome and doesn't allow for all the flexibility we could use in this
    effort.

Preppers are separated from parsers but will leverage them in order to feed
    parser-matched strings from files highlighted by a Prepper() to the
    appropriate mapping for initial obfuscation.

Preppers may specify their own priority in order to influence the order in
    which mappings are prepped. Further, Preppers have two ways to prepare
    the maps - either by generating a list of filenames or via directly pulling
    content out of select files without the assistance of a parser. A lower
    priority value means the prepper should run sooner than those with higher
    values.

For the former approach, `Prepper._get_$parser_file_list()` should be used
    and should yield filenames that exist in target archives. For the latter,
    the `Prepper._get_items_for_$map()` should be used.

Finally, a `regex_items` dict is available for storing individual regex
    items for parsers that rely on them. These items will be added after all
    files and other individual items are handled. This dict has keys set to
    parser/mapping names, and the values should be sets of items, so preppers
    should add to them like so:

self.regex_items['hostname'].add('myhostname')

        Helper that calls the appropriate Prepper method for the specified
        parser. This allows Preppers to be able to provide items for multiple
        types of parsers without needing to handle repetitious logic to
        determine which parser we're interested within each individual call.

The convention to use is to define `_get_$parser_file_list()` methods
        within Preppers, e.g. `_get_hostname_file_list()` would be used to
        provide filenames for the hostname parser. If such a method is not
        defined within a Prepper for a given parser, we handle that here so
        that individual Preppers do not need to.
