//	This is an illustration of loading data from a weird file format.
//
//	In some cases, the simplest approach is to create a cleaned-up version of the file
//	as a temporary file and then to load the data from that.
//
//	In this example, the file has line unwanted line breaks represented by consecutive
//	carriage returns, linefeeds or carriage-return/linefeed pairs.
//
//	We create a temporary file with the extra line breaks removed and load the temporary file.

// Igor can display waterfall plots using the NewWaterfall operation (choose Windows->New->Packages->Waterfall Plot).
// This requires storing your data in a 2D wave. You can also create a 3D waterfall plot using Gizmo.
//
// However, for the common case of displaying a series of spectra, you may find that a "fake waterfall plot"
// is more convenient. And it works with your original waveform or XY data.
//
// A fake waterfall plot is a regular graph with multiple waveform or XY traces where you use Igor's X and Y

// Deconstructs an Igor date/time value (seconds since 1904-01-01) into
// its component parts (year, month, dayOfMonth, etc.).
// Because it uses pass-by-reference parameters, this function can be called
// only from another user-defined function. See the Demo function below for usage.
