The eq method implements an [http://en.wikipedia.org/wiki/Equivalence_relation equivalence relation] on
non-null instances of AnyRef:
* It is reflexive: for any non-null instance x of type AnyRef, x.eq(x) returns true.
* It is symmetric: for any non-null instances x and y of type AnyRef, x.eq(y) returns true if and
only if y.eq(x) returns true.
* It is transitive: for any non-null instances x, y, and z of type AnyRef if x.eq(y) returns true and y.eq(z) returns true, then x.eq(z) returns true.
Additionally, the eq method has three other properties.
* It is consistent: for any non-null instances x and y of type AnyRef, multiple invocations of
x.eq(y) consistently returns true or consistently returns false.
* For any non-null instance x of type AnyRef, x.eq(null) and null.eq(x) returns false.
* null.eq(null) returns true.
When overriding the equals or hashCode methods, it is important to ensure that their behavior is
consistent with reference equality. Therefore, if two objects are references to each other (o1 eq o2), they
should be equal to each other (o1 == o2) and they should hash to the same value (o1.hashCode == o2.hashCode).

Buffer[A].Buffers are used to create sequences of elements incrementally by appending, prepending, or inserting new elements. It is also possible to access and modify elements in a random access fashion via the index of the element in the current sequence.
the type of the elements of the buffer
the type of the buffer itself .
@note This trait provides most of the operations of a
Bufferindependently of its representation. It is typically inherited by concrete implementations of buffers.To implement a concrete buffer, you need to provide implementations of the following methods: def apply(idx: Int): A def update(idx: Int, elem: A) def length: Int def clear() def +=(elem: A): this.type def +=:(elem: A): this.type def insertAll(n: Int, iter: Traversable[A]) def remove(n: Int): A
