Ideas/Improvements I would like to contribute

[yost-jacob]

If there is interest I would like to contribute the following:

• change m_children to be a boost/std any instead of a void* - We can the default the move and copy constructors assignment operators, and pretty sure the destructor. It at least works on the version I have been playing with.

• implement rvalue references (issue:42 ) - Its mostly pretty straightforward overloads, except for where we are deducing Type, in these cases we need to add an enable_if<is_rvalue_reference<Type&&> ,Type> or similar to prevent the universal forwarding references (Type&&) from being too greedy.

• pass path by value - a copy is made immediately in most cases anyway

• add a string_view constructor to string_path

• use other boost config helper macros to do things like add const or constexpr and noexcept where appropriate

• use macros to use std library versions of type traits, any, optional, string_view as appropriate.

• create a boost::lexical_cast based translator instead of stringstream. maybe make a macro flag to switch between them.

• find other opportunities to use string_view

• then in the far off future, a YAML parser.

• [[unlikely]] i may update the unit testing. i think its set up to use the minimal implementation of test which is deprecated and took a lot of fiddling with

If there is any real interest, I can work on the pull requests for review.
