RZPoseurWebView

####RZPoseurWebView is a library to simplify migrating from UIWebView to WKWebview.####

Features:

• Near drop-in replacement for UIWebView, backed by WKWebView.
• If WKWebView is not available, RZPoseurWebView falls back on UIWebView.
• RZPoseurWebView smooths over the differences between WKWebView and UIWebView so you can migrate with ease:
  • RZPoseurWebView is delegate-compatible with UIWebViewDelegate, aside from types.
  • Supports native alerts, which WKWebView doesn't handle by default.
  • Matches UIWebView new window behavior by opening target="_blank" links in place.
