Returns a string representation of the triangle, which is unaffected. For
example, a {@link com.jme3.math.Triangle} joining (1,0,0) and (0,1,0)
with (0,0,1) is represented by:
<pre>
Triangle [V1: (1.0, 0.0, 0.0)  V2: (0.0, 1.0, 0.0)  V3: (0.0, 0.0, 1.0)]
</pre>

@return the string representation (not null, not empty)
