Running the OpenBCI GUI

We recently just tested running the OpenBCI GUI according to the docs.

However, what the documentation neglected to mention is that if you run the binary
from the archive without changing into the directory where it and its libraries are held,
then you will get the following output on the console and a nonfunctional GUI:

The font "Raleway-SemiBold.otf" is missing or inaccessible, make sure the URL is valid or that the file has been added to your sketch and is readable.
The font "Raleway-Regular.otf" is missing or inaccessible, make sure the URL is valid or that the file has been added to your sketch and is readable.
The font "Raleway-SemiBold.otf" is missing or inaccessible, make sure the URL is valid or that the file has been added to your sketch and is readable.

After we ran it from the commandline in the directory where the executable was held,
we were able to run the GUI.
