code assist do no recognize a object when it is in the form of STL iterator.

steps:
1. Define a struct colorcal and a std::vector<colorcal*>
struct colorcal

;
2. define a function to use it.
fun()
{
colorcal* c = new colorcal;
c. //when input the ".", it can be automatically change to "->", and the member variable "rgb" and "num" can be listed
// See assit.png.

std::vector<colorcal*> colorvector = new std::vector<colorcal>;
colorvector.push_back(c);
for(std::vector<colorcal*>::const_iterator it = colorvector->begin();it != colorvector->end();it++)

}
