compiler bug (kudos smuething).

fixed soon.

Merge branch 'bugfix/fix-error-on-clang-7' into 'master'

ref:extensions/dune-alugrid When building current ALUGrid with clang 7 in
optimized mode (-O3), I get assertion errors during grid construction. I
traced the problem down to the utility function cyclicReorder(), which
contains a rather complicated expression that lacks intermediate sequence
points. This seems to horribly trip up clang's optimizer.

Fixed by splitting the offending expression into separate statements.

Closes [#50]

This introduces a boolean projectInside_ to enable or disable projection of
