## Detailed Description

Example: how to use 64-bit mode.

By default BitMagic uses 32-bit address mode even when if it is compiled for 64-bit version. This way it supports 2^32-1 address space.

There are two ways to run BitMagic in 64-bit address mode:

1. define BM64ADDR in your project Or
2. include "bm64.h"

Limitations:

- you CANNOT use 32-bit and 64-bit in the same compilation unit.
- Current implementation internally is 48-bit (which is a lot), so your range will be [0..2^48-1]
- 32-bit vectors can be serialized and read as 64-bit, but not vice versa.
