GPU running fixed

bugfix in params.device

output contains gene names instead of STRING IDs

Datasets are now taken from STRING v12.0
model.py - batch_size and lr defaults are 32 and 1e-4 respectively
commands are edited with respect to new version of STRING

0.1.3 fixed max_len bug in dataset.py (was not transfered first due to a wrong final version in previous repository)

Comments, arguments and outdated code have to be cleaned, the version still needs some testing

Working commands: predict, test, string_dataset_create
train and predict_string are still in progress

2. Train function transferred (needs to be checked)
3. Minor changes

First commit of the SENSE-PPI (version 0.1.0, unfinished), only "senseppi predict" is working. Everything else still has to be transferred.
