title: Setting up global variable in SPA (Hot Towel)
body: <p>I want to have a global variable that is accessible to modify in any view in my application. I am wondering what this the best way to do so when using hot towel. Currently, I am declareing this variable in my shell.js and referencing this in subsequent views.
  My shell.js returns the global variable. My other views have the shell defined at the top like <code>define(['viewmodels/shell'], function(shell){}</code> and I access the shell variable like <code>shell.variablename</code>. I am wondering if this is the best way of handling variables that need to be accessed by more than one view.</p>
