Initial import of cassowary-0.50, an incremental constraint solving

toolkit that efficiently solves systems of linear equalities and
inequalities, into the NetBSD packages collection.

Constraints may be either requirements or preferences.  Client code
specifies the constraints to be maintained, and the solver updates the
constrained variables to have values that satisfy the constraints.
Version 0.50 of the solving toolkit adds support for a one-way finite
domain subsolver.

+A technical report is included in the distribution that describes the

+Additionally, the distribution contains toy sample applications
+written in Smalltalk, C++, Java, and Python, and a more complex
+example Java applet, the "Constraint Drawing Application".
