Support for seq2seq task

[szamani20]

Hello!
I read the documentation and tried to run one of the notebook samples on Colab while replacing one of the classification tasks with a seq2seq task (e.g. text summarization). However, I ran into many errors and unfortunately neither in the issues nor in the documentation it was clear as to whether Jiant supports seq2seq tasks or not.
I was wondering if someone could clarify this for me. Does Jiant support seq2seq tasks (such as translation, text summarization, etc.)? If so, can you please provide an example? If not, do you know of any similar library that supports seq2seq tasks as well.
Thank you!
