$FUNCNAME$
   FT_AMEDIAN()
$CATEGORY$
   Array
$ONELINER$
   Find middle value in array, or average of two middle values
$SYNTAX$
   FT_AMEDIAN( <aArray> [, <nStart> [, <nEnd> ] ] )
	      --> nMedian
$ARGUMENTS$
   <aArray> is the array containing the elements to be averaged.

   <nStart> is the first array element to include,
   defaults to first element.

   <nEnd> is the last array element to include,
   defaults to last element.
$RETURNS$
   The median average of the array elements
$DESCRIPTION$
   This function sorts the elements of a numeric array and
   then returns the value in the middle element of the sorted
   array.  If there is no exact middle value, then it returns
   the average of the two middle values.  Half of the elements
   are > median and half are < median.  A median average may
   more reflect a more useful average when there are extreme
   values in the set.
$EXAMPLES$
   FT_AMEDIAN( aArray )      // Return Median for entire array

   FT_AMEDIAN( aArray, 2)    // Return Median for elements from 2 to end

   FT_AMEDIAN( aArray, ,9)   // Return Median for 1st 9 elements

   FT_AMEDIAN( aArray,8,40 ) // Return Median for elements 8 to 40
