a parameter hierarchy container directly.  That way, the data
structure is separated from the various ways to fill it.

Having a parser class inherit from a container is certainly not
a good design.  However, it is the simplest way to get rid of
the container implementation and still be 100% backward-compatible.
I will deprecated a few container-related methods in the near
future.

class.  This new class ParameterTree holds hierarchical sets of
string-based key/value pairs.  Input from streams/files-in-different-formats/
command-lines etc is expected to be implemented in separate parser code.

The usage and implementation is the one from the ConfigParser class.
We may want to discuss whether there are better designs/implementations
for this.

1. There might have a previous erasion and therefore use_count is zero.
2. list_->chunks_[i] is a smartpointer and therefore always true

While at it, save precision and width in addition to the flags and make sure
it can be used by multiple compilation units.

I'm actually going to need this class in PDELab.  Of course, I could just use
!AlwaysFalse<T>::value instead, but that makes the code even harder to
understand.

If there is an implementation available in std or std::tr1 we fall back to
that.

Often the configuration file is given on the command line.  However,
configuration entries can also be given on the command line, and should
usually take precedence over those from a file.  With these changes it is
possible to read entries from the command line, possibly setting one
configuration entry to the name of a config file in the process.  The
configuration file can then be parsed, setting entries, which have not been
set on the command line.  Entries which already have been set on the command
line will retain their command-line values.
