Detailed Description

Base class for UFC code generated by FFC for DOLFIN with option -l.

/// A note on the order of trial and test spaces: FEniCS numbers
/// argument spaces starting with the leading dimension of the
/// corresponding tensor (matrix). In other words, the test space is
/// numbered 0 and the trial space is numbered 1. However, in order
/// to have a notation that agrees with most existing finite element
/// literature, in particular
///
///     a = a(u, v)
///
/// the spaces are numbered from right to
///
///     a: V_1 x V_0 -> R
///
/// .. note::
///
///     Figure out how to write this in math mode without it getting
///     messed up in the Python version.
///
/// This is reflected in the ordering of the spaces that should be
/// supplied to generated subclasses. In particular, when a bilinear
/// form is initialized, it should be initialized as
///
/// .. code-block:: c++
///
///     a(V_1, V_0) = ...
///
/// where ``V_1`` is the trial space and ``V_0`` is the test space.
/// However, when a form is initialized by a list of argument spaces
/// (the variable ``function_spaces`` in the constructors below, the
/// list of spaces should start with space number 0 (the test space)
/// and then space number 1 (the trial space).
