[2014-11-26] Challenge #190 [Intermediate] Words inside of words
https://www.reddit.PI:KEY
#Description
This weeks challenge is a short yet interesting one that should hopefully help you exercise elegant solutions to a
problem rather than bruteforcing a challenge.
#Challenge
Given the wordlist [enable1.txt](http://www.joereynoldsaudio.com/enable1.txt), you must find the word in that file
which also contains the greatest number of words within that word.
For example, the word 'grayson' has the following words in it
Grayson
Gray
Grays
Ray
Rays
Son
On
Here's another example, the word 'reports' has the following
reports
report
port
ports
rep
You're tasked with finding the word in that file that contains the most words.
NOTE : If you have a different wordlist you would like to use, you're free to do so.
#Restrictions
* To keep output slightly shorter, a word will only be considered a word if it is 2 or more letters in length
* The word you are using may not be permuted to get a different set of words (You can't change 'report' to 'repotr' so
that you can add more words to your list)
#Finally
Have a good challenge idea?
Consider submitting it to /r/dailyprogrammer_ideas

File metadata management
------------------------
The `trac.mimeview` package centralizes the intelligence related to
file metadata, principally concerning the `type` (MIME type) of the
content and, if relevant, concerning the text encoding (charset) used
by the content.
There are primarily two approaches for getting the MIME type of a
given file, either taking advantage of existing conventions for the
file name, or examining the file content and applying various
heuristics.
The module also knows how to convert the file content from one type to
another type.
In some cases, only the `url` pointing to the file's content is
actually needed, that's why we avoid to read the file's content when
it's not needed.
The actual `content` to be converted might be a `unicode` object, but
it can also be the raw byte string (`str`) object, or simply an object
that can be `read()`.
.. note:: (for plugin developers)
The Mimeview API is quite complex and many things there are
currently a bit difficult to work with (e.g. what an actual
`content` might be, see the last paragraph of this description).
So this area is mainly in a ''work in progress'' state, which will
be improved along the lines described in :teo:`#3332`.
In particular, if you are interested in writing `IContentConverter`
and `IHTMLPreviewRenderer` components, note that those interfaces
will be merged into a new style `IContentConverter`. Feel free to
contribute remarks and suggestions for improvements to the
corresponding ticket (#3332 as well).

A rendering context specifies ''how'' the content should be rendered.
It holds together all the needed contextual information that will be
needed by individual renderer components.
To that end, a context keeps track of the Href instance (`.href`) which
should be used as a base for building URLs.
It also provides a `PermissionCache` (`.perm`) which can be used to
restrict the output so that only the authorized information is shown.
A rendering context may also be associated to some Trac resource which
will be used as the implicit reference when rendering relative links
or for retrieving relative content and can be used to retrieve related
metadata.
Rendering contexts can be nested, and a new context can be created from
an existing context using the call syntax. The previous context can be
retrieved using the `.parent` attribute.
For example, when rendering a wiki text of a wiki page, the context will
be associated to a resource identifying that wiki page.
If that wiki text contains a `[[TicketQuery]]` wiki macro, the macro will
set up nested contexts for each matching ticket that will be used for
