/*
 * Struct for tag parsing information
 * name   - The name of the tag, i.e. V for %V
 * params - A string specifying all of the tags parameters, each
 *          character representing a single parameter.  Valid
 *          characters for parameters are:
 *             I - Required integer
 *             i - Nullable integer
 *             S - Required string
 *             s - Nullable string
 *             F - Required file name
 *             f - Nullable file name
 *             C - Required WPS code
 *          Any nullable parameter may be replaced in the WPS file
 *          with a '-'.  To specify that parameters may be left off
 *          altogether, place a '|' in the parameter string.  For
 *          instance, with the parameter string...
 *             Ii|Ss
 *          one integer must be specified, one integer can be
 *          specified or set to default with '-', and the user can
 *          stop providing parameters at any time after that.
 *          To specify multiple instances of the same type, put a 
 *          number before the character.  For instance, the string...
 *             2s
 *          will specify two strings.  An asterisk (*) at the beginning of the
 *          string will specify that either all or none of the optional
