Thanks:

• I would like to thank Bertram Bitsch for his enormous support during the development of this code and for continuing to use the code together with his students.
• I would like to thank Cornelis Dullemond for providing the solver which (in adapted version) is used to solve the gas viscous disk equation and dust transport equation.
• I would like to thank everyone, who has already used chemcomp in their work and has contributed in fixing small bugs.
