Decreases the value of the counter by delta. If delta is not given,
decreases the value of the counter by 1.
Will throw an error if used outside of a change callback.
Increases the value of the counter by delta. If delta is not given,
increases the value of the counter by 1.

Returns the counter value, so that a JSON serialization of an Automerge document represents the counter simply as an integer.
Returns the counter value as a decimal string. If x is a counter object,
this method is called e.g. when you do ['value: ', x].join('') or when
you use string interpolation: value: ${x}.
A peculiar JavaScript language feature from its early days: if the object
x has a valueOf() method that returns a number, you can use numerical
operators on the object x directly, such as x + 1 or x < 4.
This method is also called when coercing a value to a string by
concatenating it with another string, as in x + ''.

The most basic CRDT: an integer value that can be changed only by incrementing and decrementing. Since addition of integers is commutative, the value trivially converges.
