Cleanup fft_buffer
Remove matplotlib import
Store integers for defining channels as attributes in the class

This way you can identify a channel with self.O1 for example.
Fix misuse of self.ch_bits
Hide interface and manufacturer info from instances
Cleanup these from acquireData, we'll do more intelligent things soon
Pre-store bit slices for further easy usage
Add some comments
Use queue.empty() for sync'ing with EEG stream instead of boolean
Start using a channel mask, return the acquired data
Keep slices in self.slices

self.slices["O2"] returns the relevant slice for bit manipulation.
Save data as matlab .mat file if requested
