Begin profiling a piece of code with a custom label.

This will show up in the Profiler hierarchy. Profiler.BeginSample is conditionally compiled away using ConditionalAttribute. Thus it will have zero overhead, when it is deployed in non-Development Build.

	Profiler.BeginSample ("MyPieceOfCode");
	// do something that takes a lot of time
	Profiler.EndSample ();

using UnityEngine;
using System.Collections;

public class Example : MonoBehaviour {
    void Example() {
        Profiler.BeginSample("MyPieceOfCode");
        Profiler.EndSample();
    }
}

import UnityEngine
import System.Collections

public class Example(MonoBehaviour):

	def Example() as void:
		Profiler.BeginSample('MyPieceOfCode')
		Profiler.EndSample()
