The original string passed into the constructor

The length of the original string

The character that the index is currently on

The character previous to the current index

The character that comes after the current index

The string broken down into an array of individual characters

The string split into an array by newline characters

Jumps index to the given position

.goto( pos )

Iterates over the string, passing each character back to the callback

.each( callback )

Auto-skips over the string until it finds the end character (or regex match), and returns the result

.seek( char )
.seek( regex )
