/*
* psrose reads a file [or standard input] with azimuth and length information
* and draws a sector or rose diagram. Several options for plot layout are available.
* 2 diagrams are possible: Full circle (360) or half circle (180). In the
* latter case azimuths > 180 are reversed (-= 180). psrose are fully
* compatible with other gmtsystem v2.0 plot files and overlays.
*
* To be compatible with GMT, I assume radial distance to be "x"
* and azimuth to be "y". Hence, west = 0.0 and east = max_radius
* south/north is -90,90 for halfcircle and 0,360 for full circle
