_String Replace (for real)

				
//**************************************
// Name: _String Replace (for real)
// Description:Replaces all occurances of a given substring with another substring in a String object.
I looked for a good string replacer and all of them broke (replaced things multiple times, infinitely looped, etc), so I made one. Please let me know if this doesn't work, because if it doesn't work for you then it doesn't work for me! Thanks.

// Inputs:aSearch=The String to search
aFind=The String to find
aReplace=The String to replace aFind with
//
// Returns:Returns aSearch with all occurances of aFind replaced with aReplace
