title: Create triangular meshing of a non rectangular shape in 2D in Python
body: <p>Suppose I have a set of points defining a perimeter of a non rectangular shape in the 2d plane. </p>
  
  <p>I need a function to create a triangular meshing where I can modify the number of triangle cells and return (x,y) coordinates of each cell. </p>
  
  <p>Thank you.</p>
