+
+    \brief Determines if the sequence has more than one element, referred to as a multi-element sequence.
+    
+    sequence = a sequence
+
+    returns = 1 if the sequence is a multi-element sequence, else returns 0.
+    
+    If the size of a sequence is known it is faster comparing that size to be greater
+    than one to find out if the sequence is multi-element. But if the size of the
+    sequence is not known it is faster calling this macro than getting the size and
+    doing the previously mentioned comparison in order to determine if the sequence
+    is multi-element or not.
