Produces a mapping of extensions (with leading dot) to MIME types.
It does this by calling the C{init} function of the L{mimetypes} module.
This will have the side effect of modifying the global MIME types cache
in that module.
Multiple file locations containing mime-types can be passed as a list.
The files will be sourced in that order, overriding mime-types from the
files sourced beforehand, but only if a new entry explicitly overrides
the current entry.
@param mimetype_locations: Optional. List of paths to C{mime.types} style
files that should be used.
@type mimetype_locations: iterable of paths or L{None}
@param init: The init function to call. Defaults to the global C{init}
function of the C{mimetypes} module. For internal use (testing) only.
@type init: callable

File is a resource that represents a plain non-interpreted file
(although it can look for an extension like .rpy or .cgi and hand the
file to a processor for interpretation if you wish). Its constructor
takes a file path.
Alternatively, you can give a directory path to the constructor. In this
case the resource will represent that directory, and its children will
be files underneath that directory. This provides access to an entire
filesystem tree with a single Resource.
If you map the URL 'http://server/FILE' to a resource created as
File('/tmp'), then http://server/FILE/ will return an HTML-formatted
listing of the /tmp/ directory, and http://server/FILE/foo/bar.html will
return the contents of /tmp/foo/bar.html .
@cvar childNotFound: L{Resource} used to render 404 Not Found error pages.
@cvar forbidden: L{Resource} used to render 403 Forbidden error pages.
@ivar contentTypes: a mapping of extensions to MIME types used to set the
default value for the Content-Type header.
It is initialized with the values returned by L{loadMimeTypes}.
@type contentTypes: C{dict}
@ivar contentEncodings: a mapping of extensions to encoding types used to
set default value for the Content-Encoding header.

Create a file with the given path.
@param path: The filename of the file from which this L{File} will
serve data.
@type path: C{str}

indicating the I{Content-Type} with which this L{File}'s data
will be served if a MIME type cannot be determined based on
C{path}'s extension.
@type defaultType: C{str}
@param ignoredExts: A sequence giving the extensions of paths in the
filesystem which will be ignored for the purposes of child
lookup. For example, if C{ignoredExts} is C{(".bar",)} and
C{path} is a directory containing a file named C{"foo.bar"}, a
request for the C{"foo"} child of this resource will succeed
with a L{File} pointing to C{"foo.bar"}.

request. If L{None}, one will be created.

Parse the value of a Range header into (start, stop) pairs.
In a given pair, either of start or stop can be None, signifying that
no value was provided, but not both.
@return: A list C{[(start, stop)]} of pairs of length at least one.

Convert a start and end from a Range header to an offset and size.
This method checks that the resulting range overlaps with the resource
being served (and so has the value of C{getFileSize()} as an indirect
input).
Either but not both of start or end can be L{None}:
- Omitted start means that the end value is actually a start value
relative to the end of the resource.
- Omitted end means the end of the resource should be the end of
the range.
End is interpreted as inclusive, as per RFC 2616.
If this range doesn't overlap with any of this resource, C{(0, 0)} is
returned, which is not otherwise a value return value.
@param start: The start value from the header, or L{None} if one was
not present.
@param end: The end value from the header, or L{None} if one was not
present.
@return: C{(offset, size)} where offset is how far into this resource
this resource the range begins and size is how long the range is,
or C{(0, 0)} if the range does not overlap this resource.

Set up the response for Range headers that specify a single range.
This method checks if the request is satisfiable and sets the response
code and Content-Range header appropriately. The return value
indicates which part of the resource to return.
@param request: The Request object.
@param startAndEnd: A 2-tuple of start of the byte range as specified by
the header and the end of the byte range as specified by the header.
At most one of the start and end may be L{None}.
@return: A 2-tuple of the offset and size of the range to return.
offset == size == 0 indicates that the request is not satisfiable.
