Performance against UIWebView

[cescofry]

Although FTCoreText was not specifically created to substitute a UIWebView, some people asked me how it does compared to it. The answer is I really do not know. So I set up a "Profiler" branch with all the convenient componentes to load the view first in FTCoreTExt and then in UIWebview. Once the view load you can see on the top left corner the number of characters loaded as a reference to how performance change with different text length. It would be very helpful if someone can point out a way to do proper tests against it.
