First, FormatStudentInformation is called and prefixes the course information. |

This function produces a formatted string of the student\'s course information. |

Each column of data represents all the problems for a given sequence. For |

valid grade data, a link is created for that problem to a submission record |
|
for that problem. |

$studentInformation: A pointer to an array holding the names used to |

the name of the data to be removed. |
