Replacement for all write and read method for Buffer's instance objects.

Buffer's instance method read and write

"Use strict";

Buffer.prototype.read = function(index, dataType, offfset, end){

    offset = offset||0;

    end = end||this.length;

    return (this["read"+dataType](index, offset, end));

}

Buffer.prototype.write = function(index, dataType, offfset, end){

    offset = offset||0;

    end = end||this.length;

    return (this["write"+dataType](index, offset, end));

}

I aim to contribute to node through C/C++ add-on. This is one of the things I will create an add on for to hard code it in node.
