Expression properties should be able to take function

[mohammedzamakhan]

I tried function for expression properties, but I failed doing that, we need this feature for ng2-formly final.

         expressionProperties: {
            'templateOptions.options': function() {
              if (this.model.title === 'mr') {
                return [{
                  label: 'Male',
                  value: 'male'
                }, {
                  label: 'Female',
                  value: 'female'
                }];
              } else {
                return [{
                  label: 'Female',
                  value: 'female'
                }, {
                  label: 'Male',
                  value: 'male'
                }];
              }
            }
          }

A similar eval as this one would be nice - and nearly usable as is 😄
