// The code in this file is associated with the sample project:
// 		Samples\Programming\Automation\AutomationExample.OPJ
// For an overview of what this example is all about, please see the Notes window
// in the above OPJ.
//
// The following function refered to by script code, which is contained in the import
// filter. This function is therefore called at the end of each file import. 
// This function performs the following post-processing of the imported data:
//			Retreives values from header variables created during import.
//			Creates new Project Explorer subfolder for each file that is opened.
//			Places imported data worksheet into PE subfolder.
//			Uses those values to fill first column of worksheet with wavelength value.
//			Creates a graph of amplitude versus wavelength data.
//			Performs NLSF curve fitting to graphed data.
//			Places fit results in labels in the graph window.
//			Exports graph to disk file, in BMP format.
