Clip Extension
==============
This module works with pyperclip to provide some handy features for commandline utilities.
Instead of having the user paste text into the commandline to run your script, just let them enter `script.py !c` and resolve it automatically. Pasting into the cmd on Windows is annoying and requires a mouse-click so this can be very convenient.
Since "!i" resolves to user input, your script can accept piping with `ls | script.py !i`.

Downloady
=========
- 2016 08 16
- Downloady now uses temporary files for incomplete downloads, and renames them when finished. This helps distinguish downloads that were interrupted and should be resumed from files that just happen to have the same name, which previously would have been interpreted as a resume. This improves overall ease-of-use, simplifies the behavior of the `overwrite` parameter, and will remove duplicate work from other programs.
- Rewrote the plan creator and download function to do a better job of separating concerns and simplify the plan selector.

└───User does not request range
└───File created, full download
Possible amibiguity: If the user requests a range, and the file does not exist, does he want:
1. to fill the file with zeroes, and patch the requested bytes into their correct spot; or
2. to create the file empty, and only write the requested bytes?
I will assume #1 because that plays nicely with other Things That Can Happen, such as letting the user patch the other bytes in later.

Open Dir DL
===========
The open directory downloader
The open directory downloader.
Requires `pip install beautifulsoup4`
Requires `pip install beautifulsoup4`.
See inside opendirdl.py for usage instructions.
- 2016 08 16
- **[cleanup]** Now that Downloady uses temp files for incomplete downloads, that logic can be removed from opendirdl.
- 2016 08 10
- Fixed bug in smart_insert caused by 404's being considered falsey, triggering the 'one and only one' exception.
- Fixed bug in smart_insert where 404'd URLs were not being deleted from the database.
- Added clickable links to each directory on HTML tree pages.
- **[addition]** Added clickable links to each directory on HTML tree pages.
- **[bugfix]** Fixed bug in smart_insert caused by 404's being considered falsey, triggering the 'one and only one' exception.
- **[bugfix]** Fixed bug in smart_insert where 404'd URLs were not being deleted from the database.
- 2016 08 02
- Removed the usage of div IDs on the Tree pages by making the collapse button use `this.nextSibling`.
- Rewrote `build_file_tree` with a way simpler algorithm.
- Removed the ability to set a Node's parent during `__init__` because it wasn't fully fleshed out and doesn't need to be used anyway.
- **[cleanup]** Removed the need for div IDs on the Tree pages by making the collapse button use `this.nextSibling`.
- **[cleanup]** Rewrote `build_file_tree` with a way simpler algorithm.
- **[removal]** Removed the ability to set a Node's parent during `__init__` because it wasn't fully fleshed out and doesn't need to be used anyway.
- 2016 08 01
- Made the digest work even if you forget the http://
- **[addition]** Made the digest work even if you forget the http://
- 2016 07 29
- Moved some nested function definitions out to the top level, and made the construction of the file tree its own function. These functions really don't need to be used on their own, but they were cluttering the logic of the `tree` command.
- Renamed `Tree.listnodes` to `Tree.list_children` and the `customsort` now expects to operate on Node objects rather than `(identifier, Node)` tuples. Nodes already have their identifier so the tuple was unecessary.
- Removed `Tree.sorted_children` since it was basically a duplicate of `Tree.listnodes` and I don't know why I had both.
- Replaced all `safeprint` calls with `write` because it provides access to safeprint as well as file writing if needed.
- Replaced local `download_file` function with a call to `downloady.download_file`. It supports download continuation and removes duplicate work.

- Removed the `Downloader` class after watching [this Jack Diederich talk](https://youtu.be/o9pEzgHorH0) about unecessary classes.
- Bytespersecond is now parsed by `bytestring.parsebytes` rather than `eval`, so you can write "100k" as opposed to "100 * 1024" etc.

- Rearranged the big blocks to be in a logical order rather than alphabetical order. Walker > Downloader > other classes
- Renamed the `keep_pattern` and `remove_pattern` functions to `keep_pattern_argparse` etc to be consistent with the other functions used by the argparser. *Does not affect the commandline usage!*
- Gave the HTML tree divs a very gentle shadow and alternating colors to help with depth perception.
- Fixed some mismatched code vs comments
- Fixed the allowed characters parameter of `filepath_sanitize`, which was not written correctly but worked out of luck.

- Moved db commits to only happen at the end of a digest.
