* @example Sequencer_CSharp.cs
*
* @brief Sequencer_CSharp.cs shows how to use the sequencer to grab images
* with various settings. It relies on information provided in the
* Enumeration_CSharp, Acquisition_CSharp, and NodeMapInfo_CSharp examples.
*
* It can also be helpful to familiarize yourself with the
* ImageFormatControl_CSharp and Exposure_CSharp examples as these examples
* provide a strong introduction to camera customization.
*
* The sequencer is another very powerful tool that can be used to create and
* store multiple sets of customized image settings. A very useful application
* of the sequencer is creating high dynamic range images.
*
* This example is probably the most complex and definitely the longest. As
* such, the configuration has been split between three functions. The first
* prepares the camera to set the sequences, the second sets the settings for
* a single state (it is run five times), and the third configures the
* camera to use the sequencer when it acquires images.
*
