574f4a9664 Add double stringize trick so _MSC_FULL_VER macro gets expanded
This fixes CHAISCRIPT_COMPILER_VERSION, so it gets the compiler version number instead of the string "_MSC_FULL_VER".

This means, for example, build ids read like msvc-190023918-Debug, not msvc-_MSC_FULL_VER-Debug.

fb7f8f194c Add support for r-value parameters and unique_ptr
Notes
 * Due to the limitations for how Boxed_Value is handled

8b7fe33bf1 Fix order of operations for prefix and '*', '/'
The problem is that Prefix did not properly participate in
operator precedence. I've fixed this, at least for the moment,
by adding a final depth of precedence that can be called when
the depth gets to the bottom.

7865f8e7f2 Keep ModulePtr kompatible functions
Since use of (one of) the functions in bootstrap_stl.hpp is in a
sample, chances are there are people using them in real world
application code. Thus the backwards compatible versions.

Bjorn Fahller
5ff97979fd Pass Module by reference instead of shared ptr
This gives a small but noticeable compile time improvement as
well as a measurable, albeit not great, reduction in size of the
stdlib.

# Introduction
This document outlines the principles that drive the development of ChaiScript. ChaiScript does not intent to be the perfect tool for *every* situation, but it does intend to be a good general purpose tool for *most* situations.
# Goals
1. Trivially easy to integrate with C++ projects
2. 0 external depenencies
3. "Perfect" integration with C++
* Direct mapping between ChaiScript objects and C++ objects
* Direct mapping between ChaiScript functions and C++ functions
* Direct mapping between ChaiScript exceptions and C++ exceptions
3. Never surprise the C++ developer
* Object lifetimes managed by the stack
* Familiar syntax to C++ developers
4. Perform "well enough" to not get in the way
# Alternatives
## Sol2
If you are looking for the fastest performing scripting language and don't mind Lua, you might want to consider [sol2](https://github.com/ThePhD/sol2).
## SWIG
If you are looking for the most flexible solution to be able to support multiple target languages, consider [SWIG](http://swig.org)

Function objects (including lambdas) can be used to add type conversions

### Class Hierarchies
If you want objects to be convertable between base and derived classes, you must tell ChaiScritp about the relationship.
```
chai.add(chaiscript::base_class<Base, Derived>());

Need a tool to minimize test cases before investigating the crashes or sending

Requirements
============
ChaiScript requires a C++11 compiler to build with support for variadic
templates. It has been tested with gcc 4.6 and clang 3.1 (with libcxx). MacOS
10.8 (Mountain Lion) is also known to support the C++11 build with Apple's
clang 4.0. MSVC 2013 or newer is supports also. For more information see the build
ChaiScript requires a C++14 compiler to build with support for variadic

Notes:
=======
Current Version: 5.8.2
Current Version: 6.0.0
### Changes since 5.8.6
*6.0.0 is a massive rework compared to 5.x. It now requires a C++14 enabled compiler*
#### Compiler Requirements
* MSVC 2015 or greater
* g++ 4.9 or greater
* clang 3.6 or greater
#### Breaking Changes
* Instantiating a ChaiScript object now, by default, builds the stdlib in
* This was done to address the most common support issues of loading stdlib dynamically at runtime
* If you want the old behavior, use include/chaiscript/chaiscript_basic.hpp
* Headers have been reorganized to fully separate stdlib/parser/engine from each other (some faster builds)
* Bootstrap functions no longer return a reference to the module added to (compile time savings)
* It's now no longer possible modify AST_Nodes (compile time, runtime efficiency)
* Function annotations no longer exist (simplifies code, reduces compile time, compile size)
#### New Features Added
* Modular optimization system; this can be accessed via the ChaiScript_Basic interface
* Execution tracing capability; also accessed via ChaiScript_Basic interface
* range-based for loops `for( id : container ) { }` (much better performance than other loop types)
* If-init expressions (ala C++17)
* Support for passing r-value references to functions
* Support for containing unique_ptr
* Add helpers for exposing enum classes to ChaiScript
* Allow typed ChaiScript defined functions to perform conversions on call #303
#### Improvements
* Compile time improvements
* Compile size improvements
* Significant runtime improvements (see "Modular optimization system")
* Significant parser improvements, both with parse-time and parser initialization time (Thanks @niXman)
* Fix type conversion to bool in conditionals
#### Improvements Still Need To Be Made
* File location tracking has been rewritten; this currently means error location reporting is not as good as it was
* Tracing capability needs to be tested and vetted
### Changes since 5.8.5
* Optimize away `return` statements in lambdas also
* Allow conversions to bool in conditionals
* Don't allow `class` statements inside of scopes
* Properly error when a dynamic object non-function member is called
### Changes since 5.8.4
* Fix order of operations for prefix operators
* Make sure atomics are initialized properly
* Remove parsing of unused prefix `&` operator
### Changes since 5.8.3
* Fix case with some numeric conversions mixed with numerics that do not need conversion
### Changes since 5.8.2
* Add support for reference of pointer return types
### Changes since 5.8.1
* Allow casting to non-const & std::shared_ptr<T>
