Manolis Surligas 5d4884cf0d Add a generic clear text message sink.
For now the generic clear text message sink just prints the decoded
clear text messages in the stdout. In the future and depending the needs
of the project, the clear text messages can be forwarded at other
services on the same host or via the network.

Also the debug message source block now supports injection of artificial
errors, for more robust decoding of the Morse decoder block.

Manolis Surligas 52411357a7 Fix bug at Morse debug source block
The Morse decoder seems that works properly now. However, there is no
recovery strategy yet from undecodeable symbol sequences.

Manolis Surligas ebd07215d0 Add Morse code debug source block
Now, with the Morse code debug source block the testing of the decoder
can begin.

Add at the examples directory a small flowgraph that connects the debug
source block with the decoder.

Manolis Surligas d307d6ac34 Morse tree traversal is working
Depending the received symbol the tree is traversed towards the leafs.
At each step the corresponding decode-able character is appended at a
string buffer. 

TODOs: 
* Add logic in the decoder to retrieve the decoded words from the tree
* Create a debug source block

Manolis Surligas ca49f81761 Add morse decoder block.
The morse decoder is not yet functional. The decoding is performed
using a binary tree. Left child, corresponds to a received dot whereas
right to a received dash.

Manolis Surligas b4dd0f1e14 Add matched filter implementation for CW noise reduction
* The matched filter makes use of VOLK
* The examples directory contains a simple flowgraph that demonstrates
the performance of the matched filter
