InputStream class for decompressing DBC files

Provides InputStream implementation for reading data compressed in PKWare's Data Compression Library (DCL).

Two main classes are provided:

• BlastInputStream can be used to decompress data compressed using PkWare DCL
• DBCInputStream can be used to decompress DBC files to DBF (xBase database file format). This format is used by Brazilian Health Ministry information agency DATASUS for releasing public healthcare data.

This work is based on the following sources, refactoring it to an object-oriented design and to work as a Java InputStream.
