The namespace in which the resulting JST templates are assigned to.
##### processName ```function```
This option accepts a function which takes one argument (the template filepath) and returns a string which will be used as the key for the precompiled template object. The example below stores all templates on the default JST namespace in capital letters.
``` javascript
options: {
processName: function(filename) {
return filename.toUpperCase();
}
}
```
##### templateSettings ```object```
The settings passed to underscore when compiling templates.
