I added the maxLines as a extra security measure. Since the EDL file is externally generated by some tool of the user's choice, there is no real gurarantee what the file contains. By having this limit we at least make sure we wont use up resources, or cause a crash, due to parsing a potentially huge file. 
But I admit, I was going back and forth regarding this. 
If you think it should be removed I will remove it, but I generally hate not having at least a modicum of checks for potential external problems I have no control over...
