[Liborigin-devel] Small fixes from Ropj package

[Ivan K. <kry...@gm...>]

Dear liborigin maintainers,

As a maintainer of Ropj package[1], I had to make small fixes to
liborigin; all of them are available at [2].

I would like to propose at least some of them for merging back into
liborigin to prevent fragmentation. The changes include:

 - [3] prevent undefined behaviour caused by having invalid values in
   enums and bools (direct assignment and uninitialised stack garbage)
 - [4] prevent a small memory leak in projectTree caused by the whole
   tree being placed below the feet of the tree, preventing it from
   being freed by destructor

And a smaller change required by CRAN policy: remove explicit
reference to std::cout from outputProjectTree[5], since R extensions
are not allowed to touch stdout directly.

If you are interested, I can prepare the patches in a form convenient
for you to merge.

Best regards,
Ivan
