Make error messages potentially localizable (by making them use
sprintf-style strings rather than variable subtitution).

Now that the uverloaded operators handle subclassing properly, we can
use promotePrecedence in the compare routines, just in case we define
a subclass with even HIGHER precedence!

Handle error messages better.  Produce an error if the student answer
is a constant vector.  Prevent reduction of some negatives in order to
avoid -(a+bt).  Allow students to provide answer in terms of points
rather than vectors.

This file defines a ParametricLine class that provides an answser
checker for lines in any dimension given parametrically.  The answer
checker will recognize the line even if the point and direction vector
used by the student are not the same as the ones used by the
professor.

See the comments within the file for examples of how to use it.
