title: constrain f(x) with g(x) when minimizing f(x) in mystic?
body: <p>Hi I am new to mystic so I apologize if I ask similar questions that have been answered before.</p>
  <p>Say I have an input x (a list of length n), and a function f(x) that will map the input to a m-dimensional output space. I also have a m-dimensional constraint list that also depends on the input x (say it is g(x)), and I want to make sure the output is less than the constraint for each element of the m-dimensional list. How should I specify this in mystic?</p>
  <p>simplified example:</p>
  <pre><code>x = [1,2,3]
  output = [6, 12] # with some f(x)
  constraints = [5, 10] # with some g(x)
  </code></pre>
