EXAMPLES:
    >>> from teradataml import DataFrame, Feature, FeatureStore
    # Create teradataml DataFrame.
    >>> load_example_data('dataframe', ['sales'])
    >>> df = DataFrame("sales")
 
    # Create FeatureStore for repo 'vfs_v1'.
    >>> fs = FeatureStore("vfs_v1")
    Repo vfs_v1 does not exist. Run FeatureStore.setup() to create the repo and setup FeatureStore.
    # Setup FeatureStore for this repository.
    >>> fs.setup()
    True
 
    # Example 1: Delete the Feature 'sales_data_Feb' in the repo 'vfs_v1' using Feature object.
    # Create Feature for Column 'Feb'.
    >>> feature = Feature(name="sales_data_Feb", column=df.Feb)
    # Add the feature created above in the feature store.

    Example 2: Delete the Feature 'sales_data_Feb' in the repo 'vfs_v1' using feature name.
    # Create Feature for Column 'Jan'.
    >>> feature2 = Feature(name="sales_data_Jan", column=df.Jan)
