 /**
  * $Id$
  *
  * Created: [Apr 6, 2004]
  *
  * Defines a GEO iCalendar component property.
  *
  * <pre>
  *      4.8.1.6 Geographic Position
  *
  *         Property Name: GEO
  *
  *         Purpose: This property specifies information related to the global
  *         position for the activity specified by a calendar component.
  *
  *         Value Type: FLOAT. The value MUST be two SEMICOLON separated FLOAT
  *         values.
  *
  *         Property Parameters: Non-standard property parameters can be
  *         specified on this property.
  *
  *         Conformance: This property can be specified in  &quot;VEVENT&quot; or &quot;VTODO&quot;
  *         calendar components.
  *
  *         Description: The property value specifies latitude and longitude, in
  *         that order (i.e., &quot;LAT LON&quot; ordering). The longitude represents the
  *         location east or west of the prime meridian as a positive or negative
  *         real number, respectively. The longitude and latitude values MAY be
  *         specified up to six decimal places, which will allow for accuracy to
  *         within one meter of geographical position. Receiving applications
  *         MUST accept values of this precision and MAY truncate values of
  *         greater precision.
  *
  *         Values for latitude and longitude shall be expressed as decimal
  *         fractions of degrees. Whole degrees of latitude shall be represented
  *         by a two-digit decimal number ranging from 0 through 90. Whole
  *         degrees of longitude shall be represented by a decimal number ranging
  *         from 0 through 180. When a decimal fraction of a degree is specified,
  *         it shall be separated from the whole number of degrees by a decimal
  *         point.
  *
  *         Latitudes north of the equator shall be specified by a plus sign (+),
  *         or by the absence of a minus sign (-), preceding the digits
  *         designating degrees. Latitudes south of the Equator shall be
  *         designated by a minus sign (-) preceding the digits designating
  *         degrees. A point on the Equator shall be assigned to the Northern
  *         Hemisphere.
  *
  *         Longitudes east of the prime meridian shall be specified by a plus
  *         sign (+), or by the absence of a minus sign (-), preceding the digits
  *         designating degrees. Longitudes west of the meridian shall be
  *         designated by minus sign (-) preceding the digits designating
  *         degrees. A point on the prime meridian shall be assigned to the
  *         Eastern Hemisphere. A point on the 180th meridian shall be assigned
  *         to the Western Hemisphere. One exception to this last convention is
  *         permitted. For the special condition of describing a band of latitude
  *         around the earth, the East Bounding Coordinate data element shall be
  *         assigned the value +180 (180) degrees.
  *
  *         Any spatial address with a latitude of +90 (90) or -90 degrees will
  *         specify the position at the North or South Pole, respectively. The
  *         component for longitude may have any legal value.
  *
  *         With the exception of the special condition described above, this
  *         form is specified in Department of Commerce, 1986, Representation of
  *         geographic point locations for information interchange (Federal
  *         Information Processing Standard 70-1):  Washington,  Department of
  *         Commerce, National Institute of Standards and Technology.
  *
  *         The simple formula for converting degrees-minutes-seconds into
  *         decimal degrees is:
  *
  *           decimal = degrees + minutes/60 + seconds/3600.
  *
  *         Format Definition: The property is defined by the following notation:
  *
  *           geo        = &quot;GEO&quot; geoparam &quot;:&quot; geovalue CRLF
  *
  *           geoparam   = *(&quot;;&quot; xparam)
  *
  *           geovalue   = float &quot;;&quot; float
  *           ;Latitude and Longitude components
  *
  *         Example: The following is an example of this property:
  *
  *           GEO:37.386013;-122.082932
  * </pre>
