Invoke a Downloader object to get data from
the Record. It will check to see if the necessary
files are already downloaded and use those instead of
querying FDSys. Downloaders are the endpoint for raw data.
Required arguments:
start : In form 'YYYY-MM-DD.' This is the day/start day you want.
Optional arguments:
parse : Defaults to True. This tells the downloader whether you just want
the raw files, or if you also want it to extract data from the HTML.
(Default means yes, give me the data.)
end : Same form as start. This is the end date.
outpath : Output path RELATIVE TO the present working directory. Defaults
to 'output' and works fine when you run it from the repo's root
directory.
do_mode : Specify what kind of data you want from the parser.
If do_mode is not set, the downloader will do absolutely zilch.
do_mode can take the following values:
json : write json files in a /json directory for that
day of the Record.
es : Specify the URL and index of an ElasticSearch cluster with
arguments es_url and index, and it will pass each file to
that cluster for indexing. WARNING: This doesn't handle any
mappings, and it doesn't check to see if records are already
there, so it will overwrite old files in the same index
WITHOUT versioning.
also specify:
es_url : ElasticSearch cluster url
index : ElasticSearch cluster index
yield : For each day of the Record the user specifies,
the downloader acts like a generator, yielding that day's
"crfile" dictionary.

Optional arguments:
parse : Defaults to True. This tells the downloader whether you just want
the raw files, or if you also want it to extract data from the HTML.
(Default means yes, give me the data.)
end : Same form as start. This is the end date.
outpath : Output path RELATIVE TO the present working directory. Defaults
to 'output' and works fine when you run it from the repo's root
directory.
do_mode : Specify what kind of data you want from the parser.
If do_mode is not set, the downloader will do absolutely zilch.
do_mode can take the following values:
json : write json files in a /json directory for that
day of the Record.
es : Specify the URL and index of an ElasticSearch cluster with
arguments es_url and index, and it will pass each file to
that cluster for indexing. WARNING: This doesn't handle any
mappings, and it doesn't check to see if records are already
there, so it will overwrite old files in the same index
WITHOUT versioning.
also specify:
es_url : ElasticSearch cluster url
index : ElasticSearch cluster index
yield : For each day of the Record the user specifies,
the downloader acts like a generator, yielding that day's
"crfile" dictionary.
