Rationalize the denominator of $\frac{\sqrt{5}+\sqrt{2}}{\sqrt{5}- \sqrt{2}}$. The answer can be written as $\frac{A+B\sqrt{C}}{D}$, where $A$, $B$, $C$, and $D$ are integers, $D$ is positive, and $C$ is not divisible by the square of any prime. If the greatest common divisor of $A$, $B$, and $D$ is 1, find $A+B+C+D$.
