// Templates can call external functions. Any function that is callable in   //
// normal scope can be used: global PHP functions, or user functions.        //
// Functions will be called with the template variable being the first       //
// parameter, and other params after.                                        //
//                                                                           //
// Example: `{$name|strtoupper}` maps to `strtoupper($name)`                 //
// Example: `{$name|substr:0,3}` maps to `substr($name, 0, 3)`               //
