"""Data Mapper Class.
This class represents a generic parent class for mapping between keys and data samples.
The class represents a subclass/child class of data.Dataset, inheriting its functionality.
This class is composed of a __init__ constructor, a __getitem__(), supporting fetching a data sample for a given key, and __len__(), which returns the size of the dataset.
Args:
X (HDF5 datafile): hierarchically organized input data
y (HDF5 datafile): hierarchically organized output data
Returns:
input_data (torch.tensor): Tensor representation of the input data
label_data (torch.tensor): Tensor representation of the output data
int: lenght of the output
Raises:
None
