// InlineObject represents an inline object within a block object.
// It consists of several things:
// - A start position, which indicates where in the content it should start
// - An end position, which indicates where in the content it should end.
//
// Inline objects can be several types of things (bold, URL, emphasis, etc),
// so it is a method interface.
