== NSDateCalculations

The goal to this library is to provide an easy interface for doing calculations with dates in Objective C (mac + iphone).

To use, simply drop the DateCalculations subdirectory inside your project and require "NSDate+Calculations.h".

Currently implemented methods:

+ (NSDate *)dateWithYear:(int)year month:(int)month day:(int)day hour:(int)hour minute:(int)minute second:(int)second;
+ (NSDate *)createDate:(int)year month:(int)month day:(int)day hour:(int)hour minute:(int)minute second:(int)second; /* DEPRECATED */
