Apply orientation changes to the wind components.
| uvwt | is a float array of the three components, u, v, w. The components are transformed and then written back into uvwt. |

Apply the current orientation to 2D components.
This is like applyOrientation(), except only the u and v components are transformed. A 2D transformation is the same as 3D where w is zero, but this is more convenient to call for 2D instruments. Note this only works for orientations where the result is in the same plane, such as flipped. Use applyOrientation() with a zero w component to transform a 2D vector into 3D.

| bool WindOrienter::handleParameter | ( | const nidas::core::Parameter * | parameter, |
| const std::string & | name ) |
If the given parameter is "orientation", call setOrientation() with the value.
Throws InvalidParameterException if the parameter is the wrong length or type or the value does not match one of the supported orientations. Return true if the parameter was handled, false otherwise. Pass name to include a sensor name in log and exception messages.

| void WindOrienter::setOrientation | ( | const std::string & | orientation, |
| const std::string & | name = "" ) |
Parse the orientation parameter and set the vectors which translate the axes and signs of the wind sensor components.
The parameter must be one string: 'normal' (default), 'down', 'lefthanded', 'flipped' or 'horizontal'. Throws InvalidParameterException if the string cannot be parsed. Pass name to include an identifying name in log messages about which sensor is being oriented.

Wind component sign conversion.
Also used for unusual sonic orientations, as when the sonic is hanging down, and the sign of v is flipped.

Index transform vector for wind components.
Used for unusual sonic orientations, as when the sonic is hanging down, when the usual sonic w axis becomes the new u axis, u becomes w and v becomes -v.

Is the sonic oriented in a unusual way, e.g.
upside-down, etc?
