Equation

[Shaofanl]

Equation is a combination of a str called content and a dict called parameters.

For instance:
an equation is:

      "equation": {
        "content": "\\frac{ d([Pcl]) }{ dt } = {{alpha}} * [Pcl] + {{beta}}",
        "parameters": {
          "alpha": 0.1,
          "beta": "K_1"
        }

can be rendered as:
\frac{ d([Pcl]) }{ dt } = 0.1 * [Pcl] + K_1

Render function in JS is:

function render(e) { 
  var res = e.content;  
  for (var key in e.parameters) 
    res=res.replace('{{'+key+'}}', e.parameters[key]); 
  return res; 
}
