Options

Add custom 'fast fiber call' implementation to comparison. 

We now cover all implementations that have a chance of being fast.
ARM implementations for our 'fast fiber call' are still missing. After we add them we decide on how to proceed.

## deboost.context
"Deboostified" version of boost.context (coroutines), Plain and simple C API for context switching. Easy build on multiple platforms.
### Build
#### Currently supported platforms
- Windows (x86_64, Win32)
- Linux (x86_64/x86)
- OSX (x86_64/x86)
- Android (ARM/x86/ARM64/x86_64)
- iOS (Arm64, Arm7, x86_64, i386)
#### iOS
I've made an extra xcode project files for iOS ```projects/xcode/fcontext``` because I didn't know how to set different ASM files for each ARM architecture in cmake. So If you know how to do it, I'd be happy if you tell me.
So, you can use the included toolchain file or use your own, just define _IOS_ to include the xcode project instead of generating it with cmake.
```
cd deboost.context
mkdir .build
cd .build
cmake .. -DCMAKE_TOOLCHAIN_FILE=../cmake/ios.toolchain.cmake -G Xcode
```
### Usage
Link your program with fcontext.lib/libfcontext.a and include the file _fcontext.h_.
See _include/fcontext/fcontext.h_ for API usage.
More info is available at: [boost.context](http://www.boost.org/doc/libs/1_60_0/libs/context/doc/html/index.html)
### Credits
- Boost.context: This library uses the code from boost.context [github](https://github.com/boostorg/context)
### Thanks

# INFORMATION / HELP
#
# The following variables control the behaviour of this toolchain:
#
# IOS_PLATFORM: OS (default) or SIMULATOR or SIMULATOR64 or TVOS or SIMULATOR_TVOS
# OS = Build for iPhoneOS.
# SIMULATOR = Build for x86 i386 iPhone Simulator.
# SIMULATOR64 = Build for x86_64 iPhone Simulator.
# TVOS = Build for AppleTVOS.
# SIMULATOR_TVOS = Build for x86_64 AppleTV Simulator.
# CMAKE_OSX_SYSROOT: Path to the iOS SDK to use. By default this is
# automatically determined from IOS_PLATFORM and xcodebuild, but
# can also be manually specified (although this should not be required).
# CMAKE_IOS_DEVELOPER_ROOT: Path to the Developer directory for the iOS platform
# being compiled for. By default this is automatically determined from
# CMAKE_OSX_SYSROOT, but can also be manually specified (although this should
# not be required).
# ENABLE_BITCODE: (1|0) Enables or disables bitcode support. Default 1 (true)
# ENABLE_ARC: (1|0) Enables or disables ARC support. Default 1 (true, ARC enabled by default)
# ENABLE_VISIBILITY: (1|0) Enables or disables symbol visibility support. Default 0 (false, visibility hidden by default)
# IOS_ARCH: (armv7 armv7s arm64 i386 x86_64) If specified, will override the default architectures for the given IOS_PLATFORM
# OS = armv7 armv7s arm64
# SIMULATOR = i386
# SIMULATOR64 = x86_64
# TVOS = arm64
# SIMULATOR_TVOS = x86_64
#
# This toolchain defines the following variables for use externally:
#
# XCODE_VERSION: Version number (not including Build version) of Xcode detected.
# IOS_SDK_VERSION: Version of iOS SDK being used.
# CMAKE_OSX_ARCHITECTURES: Architectures being compiled for (generated from
# IOS_PLATFORM).
#
# This toolchain defines the following macros for use externally:
#
# set_xcode_property (TARGET XCODE_PROPERTY XCODE_VALUE XCODE_VARIANT)
# A convenience macro for setting xcode specific properties on targets.
# Available variants are: All, Release, RelWithDebInfo, Debug, MinSizeRel
# example: set_xcode_property (myioslib IPHONEOS_DEPLOYMENT_TARGET "3.1" "all").
#
