<commit_before>bdmem: Big Data Memory Library
================================

A durable heterogeneous memory-like resource management library. It supports In-place persistent Java object programming.

### Features:

* In-place data storage on local non-volatile memory
* In-place generic Java object persistence
* Lazily data object loading
* Any mappable device could be used as a non-volatile memory resource
* Reclaim allocated memory when it is no longer used
* Hierarchical cache pool  for massive data caching
* A set of persistent data structures is provided by bdmemgeneric project

### How to use it ?

#### Define a durable class:
