3     **	SP_SUBSTRING_COUNT
4     **
5     **	A utility procedure to count the number of times a given substring
6     **	occurs in a given string. This can be done in a case sensitive, or 
7     **	case insensitive mode. By default it would be case sensitive. Can be
8     **	used by any procedure, although currently called by sp_spaceusage* set
9     **	of procedures.
10    **	
11    **	Paramter
12    **		@str		- The original string.	
13    **		@substr		- The substring whose occurance within @str is
14    **				  to be counted.
15    **		@casesensitive	- Whether case sensitive mode/not?
16    **	
17    **	Returns
18    **		- The number of times the substring occurs in string.
19    **
20    **		0 - if all goes well
21    **		1 - substring not found
