This function generates the column headings for the chart.

=over 4

Inputs: $CacheData, $keyID, $headings, $spacePadding

$CacheData: pointer to a hash tied to the cached data database

$keyID: a pointer to an array containing the names of the data 
held in a column and is used as part of a key into $CacheData

$headings: The names of the headings for the student information

$spacePadding: The spaces to go between columns

Output: $Str

$Str: A formatted string of the table column headings.
