Outdated example .grt files

[narner]

It looks as though the example data-sets may be out of date with some of the latest changes in the GRT. At the top of the example datasets, there's the line GRT_LABELLED_CLASSIFICATION_DATA_FILE_V1.0.

In line 2326 of GestureRecognitionPipeline.cpp, there's the following check:

	//Load the file header
	file >> word;
	if( word != "GRT_PIPELINE_FILE_V3.0" ){
        errorLog << __GRT_LOG__ << " Failed to read file header" << std::endl;
		file.close();
        return false;
	} 

whereas the top of the example datasets contain the following line:

GRT_LABELLED_CLASSIFICATION_DATA_FILE_V1.0

So, when importing one of the example datasets into an instance of a pipeline:

virtual bool load(const std::string &filename) override;

The result will always be false.
