push_unique

PUSH_UNIQUE adds values to the stack tail for values not already present

Description:
Function to add values to the stack tail for values not already in the
stack.

Syntax:
Stack=PUSH_UNIQUE(Stack,Vals);

Input Parameters:
o Stack: A one-dimensional column vector used to store neuron indices.
o Vals: A one-dimensional column vector (may be scalar) of neuron indices 
    to be added to the Stack.

Output Parameters:
o Stack: A one-dimensional column vector used to store neuron indices.

Example:
>> Stack=[1; 3; 4];
>> Stack=push_unique(Stack,[1; 5; 2])
