*****ISSUES YOU MAY HAVE*******
lchttps.cpp "if you have issues with this file do this"
add this to includes list
#include <unistd.h>


*****MUST DO BEFORE COMPILING LC******
Magic part to make this work for LC to run

adjust this line in bnf.cpp "sharelib folder"


you'll see this around line 45-50ish

static bnf __instance;
bnf* bnf::instance()
{
	
	return &__instance;
}

but for LC to run correctly "thank you gcc48" NOT!! it must be this way.

bnf* bnf::instance()
{
	static bnf __instance;
	return &__instance;
}

IF YOU DO NOT DO THIS, YOU WILL NEVER BE ABLE TO USE THESE FILES ANYWHERE
SIGSEV fault will happen instantly and it will point to a m_pool error.

Issue is around trying to do some memory shit before the main thread is even started.
this fixes the compiling issues for gcc48
