* A convenience default bootstrapper that exposes static bootstrap methods which language runtimes that need the very
* default behavior can use with minimal setup. When first referenced, it will create a dynamic linker with default
* settings for the {@link DynamicLinkerFactory}, and its bootstrap methods will create {@link MonomorphicCallSite} for
* all call sites. It has two bootstrap methods: one creates call sites that use the
* {@link MethodHandles#publicLookup()} as the lookup for all call sites and disregard the one passed in as the caller,
* and one that just uses the passed caller as the lookup scope. Using the public lookup one is advised if your language
* runtime has no concept of interacting with Java visibility scopes, as it results in a more lightweight runtime
* information.
