... that leads to bazillion error messages when there is an unexpected
connection error.

The EV3-object now handles the connection and sends commands via the
commInterface. This eliminates A LOT of redundant code (as Motor and
Sensor now only need a handle to the EV3-object, not connect/disconnect
functionality any more) and facilitates error handling.

Adapted (and cleaned up) error messages and warnings accordingly.

Implements a central dispatch method (handleCommand()) on the
convenience layer through which every call to the CommInterface is
now done (as opposed to directly calling the CommInterface's
methods). This mainly facilitates debugging and is in line with
the lower layer's interfaces. It slows down each call by .5us
(because function handles are used) - imo this is an acceptable
tradeoff.

Resolved Conflicts:
	source/EV3.m

The parsing is done by the process.py script.

Sphinx generates a redundant html-file 'source.html'. Each internal href,
derived from a link to a class/method/attribute, links source.html and
not the corresponding file (e.g. EV3.html when referencing EV3.connect()).
The postprocessing script now fixes these wrong links.

On linux/mac: MATLAB's virtual serial port implementation
On windows: Instrument Control toolbox

instrBrickIO is now deprecated and will be deleted in a future commit.
This is a WIP-version and Bluetooth has not been tested yet.

Using Windows, the packet size of USB packets has
to equal wMaxPacketSize defined in the so called
'endpoint descriptor' of the USB-HID (+ 1 byte with
the report ID; see HIDAPI doc)

This 'execute'-method is only implemented in Motor.m for now.

Fixes issue #45.

... without using the ID()-function. Fixes issue #50.

... and do a little clean-up.

... and delete .pdf-documentation for now

... before setting it to DeviceType.Error. This is done because sometimes
an erroneous packet slips through the comm-layer and causes mayhem in
high-level scripts, especially when polling sensor-types.

This fixes the bug where an error occured if disconnect is called while
motor is running. Motors are now explicitly stopped if they are busily
moving when resetting the devices
