'''
	Used to define encoder of the seq2seq model (The encoder is made of simple dynamic RNN network).

	Inputs:
		inputs -
		rnn_siz - number of units in the RNN layer
		number_of_layer - number of RNN layers that the model uses
		encoder_seq_len - vector of lengths (got from placeholder)
		keep_probs - dropout rate
		encoder_embed_size - size of embedding vector for encoder part
		encoder_vocab_size - number of different words that the model uses in a vocabulary
	
	Outputs:
		encoder_outputs -
		encoder_states - internal states from the RNN layer(s)
