<h3>
<hr>Description</h3>
<b>RSL_get_value</b>: Find a value in the Volume v using polar coordinate specification. The search returns the closest point. Although there is no restriction concerning azimuth values, other functions rely on the range being 0 to +360. This may change. Nexrad happened to use this range so I use it for now.
<p><b>RSL_get_value_at_h</b>: Returns a value when the coordinate is specified by ground range and height. Both ground range and height are specified in km.
<p><b>RSL_get_value_from_ray</b>: Return a value for the slant range <b>r</b>. Basically, r is converted to an index based on the gate size.
<p><b>Vget_value_from_sweep</b>: Get a value from a Sweep, <b>s</b>, given the azimuth <b>azim</b> and range <b>r</b>.
<p>

<h3>Return value</h3>
Upon successful completion, a valid floating point number is returned. Note, the value could be BADVAL.
