Solstice::ContentTypeService - Provides mappings between content-types and icons, MIMEExtensions, etc.

    use Solstice::ContentTypeService;

    my $filename = 'filename.txt';

    my $service = Solstice::ContentTypeService->new();

    my $content_type = $service->getContentTypeByFilename($filename);
    # returns 'text/plain';

    my $description = $service->getContentDescriptionByContentType($content_type);
    # returns 'Plain text file'

    my $extension = $service->getExtensionByContentType($content_type);
    # returns 'txt'

    Solstice::ContentTypeService is a service for identifying and
    depicting a file's content-type in various ways.

    How is this service useful? Let's say that you have identified a 
    file's content type as 'text/plain'. A view might wish to display an 
    appropriate icon for this content type (see Solstice::IconService), 
    as well as a 'human-readable' description, both of which can be 
    returned by this service.
