- Updates icons, licenses, and copyright

- Post processor (in beta; there are many things that need to be fixed and
  improved)

- Already adding Eigen as it will be necessary when we merge Grip and the
  eye model

If higher priority trigger had been open, it's queue would never be empty.

Webkit style (https://webkit.org/code-style-guidelines/)

Dear future me:

I'm sorry. Get ready for all those conflicts if you ever merge one of your old
branches. Since a lot of the code was being refactored at this time, they were
probably going to happen anyway.

Look on the bright side: Now everything is set to a single style.
Stay with it this time :-)

Moving from C to C++ null pointer style

This gives us sub millisecond precision.
Moves to ns elapsed time where pertinent.

Moving EyeRecToo to a public repository.
The commit history was removed as it may contain sensitive information.

Swirski and Starburst pupil detection algorithms are not included by default and
will be made available on separate repositories when the new pupil detection
plugin structure is included.

For internal use:

This is a reorganization of the build structure from:

Repository: EyeRecToo-internal
Branch: migration
