eqlms: blind example is really decision-directed
eqlms: adding true blind equalization example
scripts: adding brief usage description to update_copyright script
build: updating copyright in bootstrap.sh
build: removing entire documentation from *this* repository

  * functionality of this repository is just signal processing
  * documentation has been moved to separate internal repo
  * now that website is running and frequently maintained it isn't
    necessary to describe how to build the documentation
  * description for building documentation more of a hinderance than its
    worth
  * much easier to point to website or pre-compiled .pdf file
build/dotprod: removing sse4 version of dotprod_rrrf

  * causing compile errors on certain machines
  * since I have no way to reproduce results, I'm falling back to
    regular SSE3 version
  * SSE3 version nearly just as fast
  * dotprod_rrrf not commonly used anyway
