I took a modified version of FDUletter_example.tex - an example latex file to illustrate FDUletter.cls
Template by Brian Wood (brian.wood@oregonstate.edu).
Modified by Huang Weiran (huangweiran1998@outlook.com) to fit the need of FDU students.
And now modified by Asier Erramuzpe (aerramuzpe@mondragon.edu) to fit the need of MGEP students.
