NlpToolkit-SequenceProcessing

    For Contibutors
    ============
    
    ### Setup.py file
    1. Do not forget to set package list. All subfolders should be added to the package list.
    ```
        packages=['Classification', 'Classification.Model', 'Classification.Model.DecisionTree',
                  'Classification.Model.Ensemble', 'Classification.Model.NeuralNetwork',
                  'Classification.Model.NonParametric', 'Classification.Model.Parametric',
                  'Classification.Filter', 'Classification.DataSet', 'Classification.Instance', 'Classification.Attribute',
                  'Classification.Parameter', 'Classification.Experiment',
                  'Classification.Performance', 'Classification.InstanceList', 'Classification.DistanceMetric',
                  'Classification.StatisticalTest', 'Classification.FeatureSelection'],
    ```
    2. Package name should be lowercase and only may include _ character.
    ```
        name='nlptoolkit_math',
    ```
    
    ### Python files
    1. Do not forget to comment each function.
    ```
        def __broadcast_shape(self, shape1: Tuple[int, ...], shape2: Tuple[int, ...]) -> Tuple[int, ...]:
            """
            Determines the broadcasted shape of two tensors.
    
            :param shape1: Tuple representing the first tensor shape.
            :param shape2: Tuple representing the second tensor shape.
            :return: Tuple representing the broadcasted shape.
            """
    ```
    2. Function names should follow caml case.
    ```
        def addItem(self, item: str):
    ```
    3. Local variables should follow snake case.
    ```
    	det = 1.0
    	copy_of_matrix = copy.deepcopy(self)
    ```
    4. Class variables should be declared in each file.
    ```
    class Eigenvector(Vector):
        eigenvalue: float
    ```
    5. Variable types should be defined for function parameters and class variables.
    ```
        def getIndex(self, item: str) -> int:
    ```
    6. For abstract methods, use ABC package and declare them with @abstractmethod.
    ```
        @abstractmethod
        def train(self, train_set: list[Tensor]):
            pass
    ```
    7. For private methods, use __ as prefix in their names.
    ```
        def __infer_shape(self, data: Union[List, List[List], List[List[List]]]) -> Tuple[int, ...]:
    ```
    8. For private class variables, use __ as prefix in their names.
    ```
    class Matrix(object):
        __row: int
        __col: int
        __values: list[list[float]]
    ```
    9. Write \_\_repr\_\_ class methods as toString methods
    10. Write getter and setter class methods.
    ```
        def getOptimizer(self) -> Optimizer:
            return self.optimizer
        def setValue(self, value: Optional[Tensor]) -> None:
            self._value = value
    ```
    11. If there are multiple constructors for a class, define them as constructor1, constructor2, ..., then from the original constructor call these methods.
    ```
        def constructor1(self):
            self.__values = []
            self.__size = 0
    
        def constructor2(self, values: list):
            self.__values = values.copy()
            self.__size = len(values)
    
        def __init__(self,
                     valuesOrSize=None,
                     initial=None):
            if valuesOrSize is None:
                self.constructor1()
            elif isinstance(valuesOrSize, list):
                self.constructor2(valuesOrSize)
    ```
    12. Extend test classes from unittest and use separate unit test methods.
    ```
    class TensorTest(unittest.TestCase):
    
        def test_inferred_shape(self):
            a = Tensor([[1.0, 2.0], [3.0, 4.0]])
            self.assertEqual((2, 2), a.getShape())
    
        def test_shape(self):
            a = Tensor([1.0, 2.0, 3.0])
            self.assertEqual((3, ), a.getShape())
    ```
    13. Enumerated types should be used when necessary as enum classes.
    ```
    class AttributeType(Enum):
        """
        Continuous Attribute
        """
        CONTINUOUS = auto()
        """
        Discrete Attribute
        """
        DISCRETE = auto()
    ```
