/**
* @file
* Class for determining MIME types and file extensions.
*
* This class inspired by Chris Jean's work, here:
* http://chrisjean.com/2009/02/14/generating-mime-type-in-php-is-not-magic/
*
* It does some MIME trickery, inspired by the need to to deal with Openoffice
* and MS Office 2007 file formats -- which are often mis-interpreted by
* mime-magic, fileinfo, and the *nix `file` command.
*
* In Drupal 6, we also make use of file_get_mimetype. See:
* http://api.drupal.org/api/function/file_get_mimetype/6
* ... however this only provides a uni-directional lookup (ext->mime).
* While I don't have a specific use case for a mime->extension lookup, I think
* it's good to have in here.
* Replacement for the original islandora MimeClass.
* Does essentially the same thing, just using the built in drupal 7
* mime system.
*
* Drupal 7 will have better mime handlers. See:
* http://api.drupal.org/api/function/file_default_mimetype_mapping/7
* A nice added bonus is that this new class will put a note in watchdog when
* it encounters a filetype it doesnt know.

/*
* This is a shortlist of mimetypes which should catch most
* mimetype<-->extension lookups in the context of Islandora collections.
*
* It has been cut from a much longer list.
*
* Two types of mimetypes should be put in this list:
* 1) Special emerging formats which may not yet be expressed in the system
* mime.types file.
* 2) Heavily used mimetypes of particular importance to the Islandora
* project, as lookups against this list will be quicker and less
* resource intensive than other methods.
*
* Lookups are first checked against this short list. If no results are
* found, then the lookup function may move on to check other sources,
* namely the system's mime.types file.
*
* In most cases though, this short list should suffice.
*
* If modifying this list, please note that for promiscuous mimetypes
* (those which map to multiple extensions, such as text/plain)
* The function get_extension will always return the *LAST* extension in
* this list, so you should put your preferred extension *LAST*.
*
* e.g...
* "jpeg" => "image/jpeg",
* "jpe" => "image/jpeg",
* "jpg" => "image/jpeg",
*
* $this->get_extension('image/jpeg') will always return 'jpg'.
