+ This header defines the dynamic arrays and object arrays (i.e. arrays which
+ own their elements). Dynamic means that the arrays grow automatically as
+ needed.
+
+ These macros are ugly (especially if you look in the sources ;-), but they
+ allow us to define "template" classes without actually using templates and so
+ this works with all compilers (and may be also much faster to compile even
+ with a compiler which does support templates). The arrays defined with these
+ macros are type-safe.
+
+ Range checking is performed in debug build for both arrays and objarrays but
+ not in release build - so using an invalid index will just lead to a crash
+ then.
+
+ Note about memory usage: arrays never shrink automatically (although you may
+ use Shrink() function explicitly), they only grow, so loading 10 millions in
+ an array only to delete them 2 lines below might be a bad idea if the array
+ object is not going to be destroyed soon. However, as it does free memory
+ when destroyed, it is ok if the array is a local variable.
