## Detailed Description

Set options for reader/writer modules.

The class is used in a twofold way.

1. In combination with reader modules the class is used
   - to pass hints to the reading module, whether the input is binary and what byte ordering the binary data has
   - to retrieve information about the file contents after succesful reading.
2. In combination with write modules the class gives directions to the writer module, whether to
   - use binary mode or not and what byte order to use
   - store one of the standard properties.

The option are defined in `Options::Flag` as bit values and stored in an `int` value as a bitset.

## Member Enumeration Documentation

enum OpenMesh::IO::Options::Flag

Definitions of Options for reading and writing.

The options can be or'ed.

Enumerator:

  Default | No options.
  Binary | Set binary mode for r/w.
  MSB | Assume big endian byte ordering.
  LSB | Assume little endian byte ordering.
  Swap | Swap byte order in binary mode.
  VertexNormal | Has (r) / store (w) vertex normals.
  VertexColor | Has (r) / store (w) vertex colors.
  VertexTexCoord | Has (r) / store (w) texture coordinates.
  EdgeColor | Has (r) / store (w) edge colors.
  FaceNormal | Has (r) / store (w) face normals.
  FaceColor | Has (r) / store (w) face colors.
  FaceTexCoord | Has (r) / store (w) face texture coordinates.
  ColorAlpha | Has (r) / store (w) alpha values for colors.
  ColorFloat | Has (r) / store (w) float values for colors (currently only implemented for PLY and OFF files)
