Given that the sum of the first $n$ terms of the sequence ${a_{n}}$ is $S_{n}=-a_{n}-( \frac {1}{2})^{n-1}+2$ ($n$ is a positive integer).

1. Find the general term formula of the sequence ${a_{n}}$.
2. Let $c_{n}= \frac {n+1}{n}a_{n}$, $T_{n}=c_{1}+c_{2}+…+c_{n}$, find the value of $T_{n}$.

Present the answer in LaTex format: \boxed{Your answer}
