Anton MedvedevandGitHub fee5690347 Refactor checker to use Nature (#665) 
This PR introduces a new concept inside Expr's type checker - Nature.

It's an abstraction other reflect.Type which carries additional information about possible type, methods and builtin function.

I was able to find and fix a few bugs in type checker and optimizer. Implementation of nature concept has proven itself. As well nature will allow to bring more feature for type checker in future.

Why Nature? I was looking for a name to replace Type. Type name already carries much information, as well can be confused with reflect.Type. Nature name should be understood as "nature of the node", same as "type of the node".

Christian G. WardenandGitHub cb48887b9f Preserve The Specified Timezone In Parse (#633) 
* Preserve The Specified Timezone In Parse

When parsing a string into a Time using the optional timezone
parameter, set the location of the Time to the timezone's location so
that Format uses that timezone.

* Add More Tests for Preserving Timezone

Add test when timezone is used to parse a date-time.

Add test when timezone is irrelevant because it's a date.
