ofThread install instructions
  
  Step 0) Copy ofThread.h and ofThread.cpp to libs/openFrameworks/utils
  
  Step 1) Duplicate a project and rename it threadExample and replace testApp.h
          testApp.cpp and main.cpp with the thread demo files.
  
  Step 2) in ofMain.h add underneath the line "#include ofUtils.h"
  
  include <ofThread.h>
  
  Step 3) in of Constants.h change the line 
  
  // then the the platform specific includes:
  ifdef TARGET_WIN32
  
  To:
  
  // then the the platform specific includes:
  ifdef TARGET_WIN32
          //this is for TryEnterCriticalSection
          //http://www.zeroc.com/forums/help-center/351-ice-1-2-tryentercriticalsection-problem.html
  	#ifndef _WIN32_WINNT
                  #   define _WIN32_WINNT 0x400
          #endif
  
  Step 4) To run the demo app make sure in ofConstants.h you have 
  
  using namespace std;
  include <string>   
  include <sstream>  //for ostringsream
  include <iomanip>  //for setprecision
  
  Step 5) Also to run the demo make sure you have in ofUtils.cpp
  
  //--------------------------------------------------
  string ofToString(double value, int precision){
          stringstream sstr;
          sstr << fixed << setprecision(precision) << value;
          return sstr.str();
  }
  
  //--------------------------------------------------
  string ofToString(int value){
          stringstream sstr;
          sstr << value;
          return sstr.str();
  }
  
  And also in in ofUtils.h:
  
  string  ofToString(double value, int precision = 7);
  string  ofToString(int  value);
  
  Step 6) Add ofSleepMillis()
  
  add the line bellow to ofAppRunner.h:
  void                ofSleepMillis(int millis);
  
  and add the code bellow to ofAppRunner.cpp
  //--------------------------------------
  void ofSleepMillis(int millis){
          #ifdef TARGET_WIN32
                  Sleep(millis);                        //windows sleep in milliseconds
          #else
                  usleep(millis * 1000);        //mac sleep in microseconds - cooler :)
          #endif 
  }
