Cleaning NCQ Code

[felipejrabelo]

DO NOT NEED TO ACCEPT THIS PULL REQUEST

NCQ might have been changed locally in the author's computer (out of sync).

Just started doing some code cleaning:

• Removed a duplicated IF statement to avoid extra comparisons inside a loop.

• Started to use string interpolation instead concatenation.

• Add constants to avoid string repetitions all over the code.

All tests passed after changes !

I have notice that by starting two process of NCQ the temporary folders (tmp1, tmp2,...) can be replaced or erased by one process or another cause the code do not check if the folder already exists.

Hi Felipe,

Thanks for the pull request.

I will give this a proper check after our session (I don't want to make any changes until the sessions are complete).

Yep, for the running of the sessions we need to keep a user's code for research purposes.
