// cubepars.h - Cube Parser class definition
//
// Parse the cube state passed in on the command line
// checking for gross syntax errors.  For example, all
// 9 facelet markings for each of the six sides must
// be specified, and markings must be a printable ASCII
// character.  If the parse was successful a "FaceletCube"
// is initialized.  The FaceletCube represents the cube
// by the markings of the 54 individual facelets.  The
// FaceletCube can then be asked to validate the cube
// to determine if it is in a legal, and thus solvable,
// configuration.
