Example

func Test_NBC_2(test *testing.T) {
	DATA_amazon := bay.GetStruct("../data/train - amazon.csv")
	include := bay.GetInclFt("../data/filter - include.csv")
	exclude := bay.GetExcFt("../data/filter - exclude.csv")

	// Totally unfamiliar sentence
	// (Correct Classification!)
	// Now this data is trained

	bay.Print(DATA_amazon, include, exclude, "High quality code samples. It must be said: Mark Summerfield is a REALLY good programmer. All of the code in this book gives the impression of being well thought out. The other books had a lot of cargo cult programming, meaning the authors were going through the motions without thinking about what they were doing.")

	// Output:
	// Positive: High quality code samples. It must be said: Mark Summerfield is a REALLY good programmer. All of the code in this book gives the impression of being well thought out. The other books had a lot of cargo cult programming, meaning the authors were going through the motions without thinking about what they were doing.
