Subs resolution status

One of the most important goals of this plugin was to unleash powerful IDEA refactoring into the Perl's world. But, it's easier to say... :)

Currently

At the moment, only obvious subs invocations are resolved:

• sub()
• Package::sub()
• Package->sub() - with inheritance
• sub Package() - works, but glitchy, not recommended
• $self->sub() - with inheritance
• SUPER::sub() - with inheritance
• $obj->sub() - with inheritance, if $obj has been declared with specific type:

my Foo::Bar $obj;
...
$obj->method(); # we know that it's Foo::Bar method

Inheritance is partially implemented, refactoring of object methods better not to use yet.

What is planned

• Subs annotations usage to resolve chained invocations like $obj->method1->method2->method3
• Annotation files, to be able to define return values and prototypes for packages without those.
• Resolving constants
• Resolving imports
• Optimizing inheritance search
