Description: 
        # Code for the alpacka Python package, used to extract metadata from text data sets
        #### Folder "functions" contains functions for calculating the NCOF and TF-IDF score for a user specified data set. 
        #### The file "Pipes" contains pipelins for the two methods that can be used to create a better workflow when using the package as well as a tool for loading the data.
        #### To use the package begin by importing Pipes and then you can initiate the Data loader, NCOF, or TFIDF class. 
        #### Alter the config.ini file to change the base setup and alter the paths to your data
        
        # Walkthrough
        
        ### Initiate the data loader by calling Data_process from Pipes.
            d = Pipes.Data_process()
        Settings are loaded from the `config.ini` file. Located in the `alpacka` folder
        ### Initiate the NCOF and TF-IDF methods from Pipes.
         
        
            ncof = Pipes.NCOF_pipe()  
        	tfidf = Pipes.TFIDF_pipe()
        ### Set the data path through the `config.ini` file or through the `Data_process` class, both methods are equvilent. 
        In the `config.ini` file alter `data_file ` & `data_folder ` to the file name and path to the location of your data. 
        
            [Data]  
        	    Verbose = True  
        	    num_words = None  
        	    Supported_inputs = list  
        	    Input_data_type = list  
        	    stop_word_path = alpacka/functions/Stopord.txt  
        	    data_file = data_file_name.csv  			<-----
        	    data_folder = path\to\data\folder 			<-----
        Or your can call the `set_data_file` and `set_data_folder` and input the name of you data file and path to your data folder from the  `Data_process`class.
        
            d.set_data_file('data_file_name.csv')
            d.set_data_folder('path\to\data\folder')
        
        ### Now you should be ready to load your data.  Load the data by calling the `load_file`method from your `Data_process`class. Currently  the alpacka package only supports `.csv` files as input. 
        The required inputs of the `load_file`call is the names of the columns that contains the data and its labels. 
        
            data , labels = d.load_file( 'preprocessed_text', 'labels')
        ### Now that the data is loaded we can simply calculate our NCOF and TF-IDF score for the data set by calling the `calc_NCOF` & `calc_TFIDF`methods from their respective class. The scores will be saved wihin the classes and can be vieved and assigned to a external variable by calling `.get_Score()`.
           
        
            ncof.calc_ncof(data, labels)
            score_ncof = ncof.get_Score()
        
        	tfidf.calc_TFIDF(data, labels)
            score_tfidf = tfidf.get_Score()
        
        ### From the score the outliers can be seperated & identified by calling `.split_score()`. 
        No inputs are needed, the method is fully self contained.
        
            ncof.split_score()
            tfidf.split_score()
        
        ### Now the NCOF score is ready to be plotted, and its outliers get be viewed by calling the `.get_Pos_outliers()`& `get_neg_outliers()`.
        
        ### The TF-IDF methods requires one additional step before it is ready to be plotted. 
        This step is to identify which outliers are only occuring in the positive or negative class and is done by calling `.unique_outliers_per_class()`. 
        
            tfidf.unique_outliers_per_class()
        The results can be viewed by calling the `get_outliers_unique_neg()` & `get_outliers_unique_pos()`
        
        ### The reults can now finally be plotted by the `.scatter() `method. 
         For simplicity the method does not require any inputs, if more contoll is needed for the plot it is recomended that a custom function is created. 
         
        
            ncof.scatter()
            tfidf.scatter()
