Detailed Description
The BlinkenlightProxy class is used to enable and disable a flashing indicator light, and to set its period, via a blinkenlight device.
Constructor. Leave the access field empty to start unconnected. The current period (one whole on/off cycle) of the blinking light. If the period is zero and the light is enabled, the light is on. Set the state of the indicator light. A period of zero means the light will be unblinkingly on or off. Returns 0 on success, else -1. The BlobfinderProxy class is used to control a blobfinder device. It contains no methods. The latest color blob data is stored in blobs, a dynamically allocated 2-D array, indexed by color channel.

Blobfinder data access operator.
This operator provides an alternate way of access the actuator data. For example, given a BlobfinderProxy named bp, the following expressions are equivalent: bp.GetBlob[0] and bp[0].
