Simple interface for implementing erasure codes

This library makes use of Jesasure for Reed-Solomon as implemented by the liberasurecode library and provides its' own flat XOR-based erasure code encoder and decoder. Currently, it implements a specific class of HD Combination Codes (see "Flat XOR-based erasure codes in storage systems: Constructions, efficient recovery, and tradeoffs" in IEEE MSST 2010). These codes are well-suited to archival use-cases, have a simple construction and require a minimum number of participating disks during single-disk reconstruction (think XOR-based LRC code).
