=head2 convert_latlon_to_en

    ( $easting, $northing ) = Utils::convert_en_to_latlon( $latitude, $longitude );

Takes the WGS84 latitude and longitude and returns OSGB36 easting and northing.

=head2 convert_en_to_latlon

    ( $latitude, $longitude ) = Utils::convert_en_to_latlon( $easting, $northing );

Takes the OSGB36 easting and northing and returns WGS84 latitude and longitude.

=cut

=head2 convert_en_to_latlon_truncated

    ( $lat, $lon ) = Utils::convert_en_to_latlon( $easting, $northing );

Takes the OSGB36 easting and northing and returns WGS84 latitude and longitude
(truncated using C<Utils::truncate_coordinate>).

=cut

sub convert_en_to_latlon_truncated {
    my ( $easting, $northing ) = @_;

=head2 truncate_coordinate

    $short = Utils::truncate_coordinate( $long );

Given a long coordinate returns a shorter one - rounded to 6 decimal places -
which is < 1m at the equator, if you're using WGS84 lat/lon.

=cut

    my $in = shift;

}

=head2 trim_text

    my $text = trim_text( $text_to_trim );

Strip leading and trailing white space from a string. Also reduces all
white space to a single space.

Trim

=cut

sub trim_text {
    my $input = shift;
    for ($input) {
        last unless $_;
        s{\s+}{ }g;    # all whitespace to single space
        s{^ }{};       # trim leading
        s{ $}{};       # trim trailing
    }
    return $input;
}


=head2 cleanup_text

Tidy up text including removing contentious phrases,
SHOUTING and new lines and adding sentence casing. Takes an optional HASHREF
of args as follows.

=over

=item allow_multiline

Do not flatten down to a single line if true.

=back
