// Shorter cleaner way to add methods to an object prototype. Thank you Crockford
Function.prototype.method = function ( name, func ) {
  if (! this.prototype[name] ) { this.prototype[name] = func; return this; }
};
// And here's the ability to add multiple KVs to objects
Function.method( "methods", function ( obj ) {
  if ( typeof obj !== "object" ) return;
  for ( var key in obj ) {
    if ( ! obj.hasOwnProperty( key ) ) continue;
    this.method( key, obj[key] );
  }
});
// Example usage
String.methods({
  'to_i':       function () { return parseInt( this.match( /\d+/ )[0], 10 ); },
  'capitalize': function () { return this.charAt( 0 ).toUpperCase() + this.slice( 1 ); }
});
