# Fast Compiliing C++ Library
-----------------------------------------
In my prior attempts at developing MACE what I discovered is that compile times
would explode to unreasonable levels that hinder the rate of development more
than what can be saved by reduced typing. So I began a quest to get C++ to compile
as quickly as Java or C# and the result is this library.
One of the major drawbacks to templates is that they place everything in header and
must be compiled with every run and generate a lot of object code. With Link Time Optimization,
the benefit of inline methods mostly disapears, leaving only static vs dynamic polymorphism.
For the vast majority of applications, a virtual method call is not the bottleneck and the
increased compile times costs more than is otherwise justified; therefore, the Fast Compiling C++
library opts for virtual interfaces to handle reflection instead of template interfaces. One could
argue that both types of reflection could be useful.
Another source of slowness was the standard template library itself. Most standard template library
classes cannot be forward declared and import thousands of lines of code into every compilation unit.
Another source of slowness is the need to include headers simply because the 'size' of the object must
be known. A new utility class allows you to 'forward declare' the size required for certain types which
allows you to remove their inclusion from the header file.

/**
* @class shared_impl<T>
* @brief used to create types with reference semantics
*
* A type with reference semantics is effectively a shared pointer except that
* it is used like a Java or C# type using '.' notation instead of -> notation.
*
* It is ideal for use with classes that almost always get managed by a shared
* pointer (sockets and long-lived resources). These types are rarely, if ever
* copied by value and often by-value copy or 'deep-copy' has no real meaning.
*
* An additional feature of shared_impl<T> is that your classes implementation
* should be private and defined entirely in your source file. There should be
* no member variables defined in your types header.
*
* To make this design pattern work requires a lot of 'boiler-plate' code for
* handling assignments, moves, copies, etc that cannot be provided via tradtional
* means such as templates or base classes.
*
* To create a new type with reference semantics you place FC_REFERENCE_TYPE(type)
* inside the private section of 'type'. Then in your source file you will
* need to define your 'private' data.
*
* @code
* #include <your_type.hpp>
*
* FC_START_SHARED_IMPL( your_namespace::your_type )
* impl( int x, int y ); // custom constructor
*
* ...
* int member_variable;
* your private member variables / methods go here.
* ...
* FC_END_SHARED_IMPL
* #include <fc/shared_impl.cpp>
* @endcode
*
*
* Lastly, you will need to provide the implementation your class below. This
* implementation will need to provide the matching implementations for the
* methods declared by FC_REFERENCE_TYPE(type) in your header. To do this
* use the FC_REFERENCE_TYPE_IMPL(type)
*
* @code
* namespace your_namespace {
* FC_REFERENCE_TYPE(your_type)
* ... your methods here...
* }
* @endcode
*
* Within the body of your methods you can access your private data and members
* via using 'my->member_variable'
*
* If you want to define custom constructors for your reference type, you will
* need to implement them inside the FC_START_SHARED_IMPL block using the pattern:
*
* @code
* FC_START_SHARED_IMPL( your_namespace::your_type )
* impl( int x, int y ){} // custom constructor
* FC_END_SHARED_IMPL
* @code
*
* A limited number (3) of arguments are supported for custom constructors.
*
* Once you have defined your reference type you can use it like so:
*
* @code
* your_type val = nullptr; // create a null type
* your_type val2 = new your_type(...); // construct a new instance, unnecessary temporary heap alloc
* your_type val3(...); // constructs a new instance, more effecient
*
* val2.your_method();
* val2 = nullptr; // reset val2 to a null object
*
* val2 = val3; // val2 and val3 now reference the same data
* if( !!val2 ){} // val2 is not null
* else{} // val2 is null
* @endcode
*
* As you can see, when creating types with this method your code will
* look and act like a Java or C# garbage collected type.
*
* Often times your private methods will need to call your public methods, to achieve
* this you can use the following techinque:
*
* @code
* FC_START_SHARED_IMPL( your_namespace::your_type )
* void private_method( int x, int y ){
* auto s = self();
* s.public_method();
* }
* FC_END_SHARED_IMPL
* @code
*
* For performance reasons, it is best to only call 'self()' once and save the
* result to avoid unnecessary copies of shared pointers which require atomic
* operations.
*
