Appends a new member to the end of this object, with the specified name and the JSON
representation of the specified string.
<p>
This method <strong>does not prevent duplicate names</strong>. Calling this method with a name
that already exists in the object will append another member with the same name. In order to
replace existing members, use the method <code>set(name, value)</code> instead. However,
<strong> <em>add</em> is much faster than <em>set</em></strong> (because it does not need to
search for existing members). Therefore <em>add</em> should be preferred when constructing new
objects.
</p>

@param name
the name of the member to add
@param value
the value of the member to add
@return the object itself, to enable method chaining
