Description:
The function takes a given regular expression and evaluates each element of a given list of values against the regular expression. The match is case-insensitive. If the regular expression matches an element in the list, the list location of that element is added to a list of matched locations. The function returns the list of matched locations.

Return Values:
Returns a list of matches.

Example:

<cfset mylist = "Rob Munn|Robert Munn|RDM|Fred|Gregg|Rob">
<cfset myReturn = REListFindNoCaseMultiple("Rob[^\|]*",mylist,"|")>

<cfoutput>#myReturn#</cfoutput>
