Created normal autoconf based installer.

The usual method now works:
./configure && make && make install

Though make doesn't actually do anything, it's still header only and you
can just point your compiler at the source drectory if you wish.

Also updated the documentation.

+Errors
+=====
+
+On error, the library throws an error class indicating the type of error. The error classes are derived from the SQLITE3 error names, so if the error code is SQLITE_CONSTRAINT, the error class thrown is sqlite::exceptions::constraint. Note that all errors are derived from sqlite::sqlite_exception and that itself is derived from std::runtime_exception.
 
 *node: for NDK use the full path to your database file : `sqlite::database db("/data/data/com.your.package/dbfile.db")`*.
 
+Building and Installing
+=====
+
+The usual way works for installing:
+
+```bash
+./configure && make && sudo make install
+
+```
+
+Note, there's nothing to make, so you there's no need to run configure and you can simply point your compiler at the hdr/ directory.
