Description:
Get a count on searching string in the searched string. Simular to ListLen, however this UDF accepts a string, not a single character, as a delimiter.

Return Values:
Returns a numeric value.

Example:

<CFSET STR = "what a world what a world what a world">
<CFOUTPUT>
STR=#STR#<BR>
CountIt(STR,"what a world") = 
#CountIt(STR, "what a world")#<BR>
CountIt(STR,"world") = 
#CountIt(STR, "world")#<BR>
CountIt(STR,"d") = 
#CountIt(STR, "d")#<BR>
</CFOUTPUT>
