Segmentation fault about pyv8 HOT 1 CLOSED

The issue was caused by a wrong assumption, because the compile and eval 
method of JSEngine need a entered context; so, if you directly call those 
methods, 
it will crash in release mode and hit a assert in debug mode.

Now, I change the code to throw a exception instead of 'Segmentation fault'

Please ensure you have enter a context before use the JSEngine, or directly use 
JSContext as delegate

>>> import PyV8
>>> ctxt = PyV8.JSContext()          # create a context with an implicit global 
object
>>> ctxt.enter()                     # enter the context (also support with 
statement)
