Checks for inaccurate use of the `erase()` method.

Algorithms like `remove()` do not actually remove any element from the container but return an iterator to the first redundant element at the end of the container. These redundant elements must be removed using the `erase()` method. This check warns when not all of the elements will be removed due to using an inappropriate overload.

For example, the following code erases only one element:

    std::vector<int> xs;
    ...
    xs.erase(std::remove(xs.begin(), xs.end(), 10));

Call the two-argument overload of `erase()` to remove the subrange:

    std::vector<int> xs;
    ...
    xs.erase(std::remove(xs.begin(), xs.end(), 10), xs.end());
