#### `insert(char c, iterator i)`
```
    increment size private data member by 1
    follow i's current
    check if the length of that chunk is less than chunksize
        follow pointer to chunk current
        use index of char position private data member to get current char position
        use loop starting at the length + 1 position down to the iterator i position data member
            copy the index th character into the index+1 th position
        increment length of the chunk by 1
        set iterator i = char c
    else
        create new chunk
        follow current pointer to chunk
        go the length element and save it to a char variable
        follow pointer to chunk current
        use index of char position private data member to get current char position
        use loop starting at the length + 1 position down to the iterator i position data member
            copy the index th character into the index+1 th position
        increment length of the chunk by 1
        set iterator i = char c
        set the first thing of the newly created chunk to the saved char variable
        loop through while length / chunksize of the new chunk is not less than utilization ratio (1/2)
            get the last element of the original chunk and insert at the first element the new chunk
            decrement size of the original chunk by one
```


#### `erase(iterator i)`

```
(Move-forward method for utilization)

Decrement size private data member by 1
Follow i's current
Check if the length of that chunk is greater than 1
    Follow pointer to chunk current
    Use index of char position private data member to get current char position
    Use loop starting at the above position up to but not including the data member at position length of the chunk
        Copy the index+1th character into the indexth position
    Decrement length of the chunk by 1
    if previous chunk exists
        loop through while length / chunksize of the new chunk is not less than utilization ratio (1/4) and length / chunksize of previous chunk is greater than uilization ratio
            get the last element of the previous chunk and insert at the first element the new chunk
            decrement size of the original chunk by one
else
    Set previous chunk's next iterator to the next of current
    Set the next chunk's previous to the previous of current
    Delete current
