[V4CC] Valentina for Cocoa, Vdatabase.h

[Justin Drury]

Hi Ruslan and others...

This looks great!  Just had a quick moment to look it over, I'd like to use it in practise...

KeyValueCoding compliant...good thing.

My only style question is the usage of VSQL::xException on the SQL commands.  I know you're using 
exceptions in 2.0.  Personally I'd prefer getting back a NULL object and calling a lastError method to 
get back an NSError.  Others should chime in here.

How is Valentina init'ed, serial numbers, destroyed?  Should vDatabase or even better, the valentina 
init class have a (BOOL) valentinaInitialized; method? (For debug checks).  Could bind controls so 
they disable(demo purposes?)

Other than that, looks beautiful!  I'm sure I'll have some comments on the VCursor class!!!
