* minor fixes in Part and StaticAssert
* EulerAngles: remove the FIXME as I think the current version is fine

todo
Read/write access to special parts of a matrix can be achieved. See \link MatrixBase::part() const this \endlink for read access and \link MatrixBase::part() this \endlink for write access..
<table class="tutorial_code">
<tr><td>
Extract triangular matrices \n from a given matrix m:
</td><td>\code
m.part<Eigen::Upper>()
m.part<Eigen::StrictlyUpper>()
m.part<Eigen::UnitUpper>()
m.part<Eigen::Lower>()
m.part<Eigen::StrictlyLower>()
m.part<Eigen::UnitLower>()\endcode
</td></tr>
<tr><td>
Write to triangular parts \n of a matrix m:
</td><td>\code
m1.part<Eigen::Upper>() = m2;
m1.part<Eigen::StrictlyUpper>() = m2;
m1.part<Eigen::Lower>() = m2;
m1.part<Eigen::StrictlyLower>() = m2;\endcode
</td></tr>
<tr><td>
Special: take advantage of symmetry \n (selfadjointness) when copying \n an expression into a matrix
</td><td>\code
m.part<Eigen::SelfAdjoint>() = someSelfadjointMatrix;
m1.part<Eigen::SelfAdjoint>() = m2 + m2.adjoint(); // m2 + m2.adjoint() is selfadjoint \endcode
</td></tr>
