In Haxe, `\b` (for "backspace") and `\f` (for "form feed") are not
valid escape sequences. To make things simpler, those escape sequences
are not used in this C++ code. Those characters hexadecimal codes are
respectively 08 and 0C so they are catch when escaping control
characters. check-in: 656c695a50 user: nales tags: trunk

Usually I have only one root node in my document. The created total node
by the software is redundant. So it makes more sense to hide it by
default. check-in: ec50d4ae38 user: nales tags: trunk

The removed options are:

* `--no-ignored`;
* `--no-ignored-and-calculated`;
* `--no-indent`;
* `--total-name`.

For the moment I, nales, am the only user of this software. I developed
and implemented options that future imaginary users would want. It was a
mistake. It consumed too much time for nothing.

From now on I am developing this software for my needs. If a real user
wants a feature, this person should send me a request or a patch. check-in: 1f5a499305 user: nales tags: trunk

The previous implementation was not using smart pointers which resulted
in a lot of copies. For example when a child node was added to the
vector of the children of its parent, the node itself and its vector of
children and all its descendants were copied. This is an inefficient
process! Maybe the compiler optimized that but nothing ensure that.

We now use smart pointers so the nodes are created only once and only
the smart pointer ownership is moved. It reduces a lot of time spent in
copying data. check-in: ca9ad9fdfb user: nales tags: trunk

By default the release build is chosen because this is what most of the
users want. check-in: 4570ed6b11 user: nales tags: trunk
