Function to move to a spacified tag in a script file structure.
Move the script pointer from 1 tag (line) to another.
@param[in] Function The pointer to the function to move with.
@param[in] DecrementerTag The pointer to a string to decrement upon finding.
@param[in] IncrementerTag The pointer to a string to increment upon finding.
@param[in] Label A Label to look for.
@param[in] ScriptFile The script file structure to look in.
@param[in] MovePast TRUE to go to the element just after the found one. FALSE otherwise.
@param[in] FindOnly FALSE to change the execution point in the script file structure. TRUE otherwise.
@param[in] WrapAroundScript TRUE to go to begining when end is hit, or vise versa. FALSE otherwise.
It functions so that count starts at 1 and it increases or decreases when it
hits the specified tags. when it hits zero the location has been found.
DecrementerTag and IncrementerTag are used to get around for/endfor and
similar paired types where the entire middle should be ignored.
If label is used it will be used instead of the count.
@param[in] Function The function to use to enumerate through the
list. Normally GetNextNode or GetPreviousNode.
@param[in] DecrementerTag The tag to decrement the count at.
@param[in] IncrementerTag The tag to increment the count at.
@param[in] Label A label to look for.
@param[in,out] ScriptFile The pointer to the current script file structure.
@param[in] MovePast TRUE makes function return 1 past the found
location.
@param[in] FindOnly TRUE to not change the ScriptFile.
@param[in] WrapAroundScript TRUE to wrap end-to-begining or vise versa in
searching.
