Where can I find an elementary introduction (construction, description, main properties) to the Teichmüller space ${\cal T}\_{1,n}$ of elliptic curves with $n$-marked points?


Same question for the following associated objects: mapping class group $\Gamma\_{1,n}$ and moduli space ${\cal M}\_{1,n}={\cal T}\_{1,n}/\Gamma\_{1,n}$.


Thanks in advance for any reference.
