/*

Useful functions that deal with Apple-specific classes.
This covers both Mac OS X and iOS platforms.

Apple-specific implementations of the multi-platform
HPT-C libraries will go in those regular HPT-C folders,
not here.

This folder is for stuff that's specific to Apple
platforms and can only be called from Objective-C/C++
code. These functions can be helpful in our Apple product
GUI code, and in our Apple-specific implementations of 
the HPT-C library functions/methods.

UI* classes are for iOS
NS* classes are for Mac and may apply to iOS as well

.m and .h for Objective-C  (can be used from Obj-C++ code)
.mm and .hh for Objective-C++  (cannot be used from Obj-C)
