This is the output from the preliminary version of the "BioDevice" library.
Right now the only device implemented is Thought Technologies ProComp+. To
really flesh out the library and make sure the design "holds water," we'll need
other devices implemented -- ModularEEG, TinyEEG, BrainMaster, or otherwise.
Any takers, please raise your hand.
Here's the basic flow with comments:

All the above is default information read from the configuration file. Below
is where I actually configure the device the way I wanted it -- which is to
associate EEG modalities with Channels A & B and GSR with Channel C. Most
devices will not need this step, as they will have fixed modalities.

The "BioNode" method of handling the data streams is Jim P's brainchild. While
I have implemented it using some STL conventions (vectors and iterators), I am
thinking that he is right in that it can be made much more efficient (and
probably should be done considering the time critical nature of this part of
the system) by using straight C code.

And here comes the data from the monitoring class. Notice that Channel-C is at
a different sample rate than Channels A & B. The ProComp generates 256Hz for A
& B, while Channels C-H are 32Hz. I need to change the message a bit because
it says "Error: No value..." which is really not an error at all. The data
simply comes through the data processing node network at different rates.
BTW.... the EEG electrodes were not connected to my head, which is good sign
because if you look at the numbers, you might truly wonder if it is safe for me
to be working with electronic equipment at all. ;-) The GSR are real values,
however, as I connected those to my index and middle finger.
