      Description

      Support the Azimuthal Equidistant projection.

      This implementation does not include the Guam or Micronesia variants.

      Attached GeoServer WMS ice edge samples demonstrate output for the following projections (with lines in epsg.properties):

      (1) ice-polar-5m.png: North Polar Azimuthal Equidistant with central meridian at 0 degrees, with bounds +/-5e6 in projected coordinates (image centred on origin):

      (2) ice-oblique-7m.png: North American Oblique Azimuthal Equidistant centred on -106 degrees east and 54 degrees north, with bounds +/-7e6 in projected coordinates (image centred on origin):

      The source data is nic_autoc2016001n_pl_a.zip from the US National Ice Center, longitude/latitude graticules at 30 degree increments, and GSHHS intermediate level one shorelines.
