Update on moving core.matrix to Clojure contrib

[Alex Miller]

At this point all core.matrix contributors have signed a Clojure Contributor Agreement - thanks to everyone that took care of that promptly.

The next step is to make a public offer of contribution. All contributors can do so here:

https://github.com/mikera/core.matrix/issues/294

Just comment on the issue with "I agree"

Github ids for those needed are:

@mikera @si14 @Gerrrr @rosejn @prasant94 @fyquah95 @mschuene @tbrooks8 @grtlr @charlesg3 @bmabey @keithschulze @japonophile @danielcompton @ds923y @ejackson @siscia @eavgerinos @shark8me @Quantisan @dmarjenburgh @mjwillson @fbmnds @munk @mattrepl @farrellm @sethyuan @edwastone @nblumoe @4gh @SwamWithTurtles @adereth @cloojure @jafingerhut @durka @hokkaido @jolby @heffalump
