 The 'tree' argument is the tree to which the item is to be added.  The
 'tvb' argument is the tvbuff from which the item's value is being
 extracted; the 'start' argument is the offset from the beginning of that

 -----------------------------
 Works in the same way but also returns the value of the read bits.
 
+proto_tree_add_split_bits_ret_val()
+-----------------------------------
+Similar, but is used for items that are made of 2 or more smaller sets of bits (crumbs)
+which are not contiguous, but are concatenated to form the actual value.  The size of 
+the crumbs and the order of assembly are specified in an array of crumb_spec structures.

+proto_tree_add_split_bits_crumb()
+---------------------------------
+Helper function for the above, to add text for each crumb as it is encountered.

 proto_tree_add_bitmask() and proto_tree_add_bitmask_text()
 ----------------------------------------------------------
 This function provides an easy to use and convenient helper function
