several fixes applied

[alpham8]

Hi,

I fixed the following things:

• pattern fix (was not working with dash in channel name)
• removed reference, because it is already an object and it would anyway return a reference, so you don't need a second reference
• added getters and setters for dependency injection
• removed reading of empty lines from log file
• removed last line reading in readme, because it is an iterator and you iterate over all elements

All tests passed.

Hope this helps :-)
