[I chatted with the author of Monodraw][1] about updating this cask as
it's currently broken. His preference was for its removal as its
shareware, and will cost money once out of beta. For the time being,
it can be downloaded (with email registration) at:
http://monodraw.helftone.com/
I think respecing the authors intentions is important, and have removed
the Monodraw cask with this commit.
