Exit if hyperparameters file does not exist

[agitter]

I was testing SINGE in the Docker image and provided a hyperparameters files that did not exist. However, SINGE continued running with default hyperparameters. SINGE.sh and SINGE.m should exit with an error in this case.

Here is the start of the output:
