// Support for reading or writing a binary file. If you open the file for
// reading, calling the writing routines is an error. If you open the file
// for writing, calling the reading routines is an error. This class does
// not support read-write access. The class wraps FILE operations of fopen,
// fclose, fread, and fwrite. A hint is passed to fopen to optimize caching
// for sequential access from disk.
//
// The nested enumeration Mode supports endianness mismatches between the
// platform that created the file and the platform that is using it. The
// flags are defined as follows:
//
// FM_READ
// Read the data from disk as is (no byte swapping).
//
// FM_WRITE
// Write the data to disk as is (no byte swapping).
//
// FM_READ_AND_SWAP
// Read from disk and swap 2-, 4-, and 8-byte inputs.
//
// FM_WRITE_AND_SWAP
// Swap 2-, 4-, and 8-byte inputs and write to disk.
