Feature/new model for scalar regression. In the models/transformer.py, a model called Transformer Regressor was created.

In the models/transformer.py, a model called Transformer Regressor was created.

A new class called Transformer Regressor was created with the registry decoder in the models/transformer.py, in order to conduct a regression method such as sentiment analysis.

This is done by inheriting from Transformer Encoder and will be supposed to produce a real number as an output tensor with the shape of (N, 1,1,1) from input tensor.
