% TITLE PAGE
%   - define \title{} \author{} \date{}
%   - The default degree is ``Unknown Degree''
%     Degree can be changed using the command \iitbdegree{}
%   - The default department is ``Unknown Department''
%     The department can be changed using the command \department{}
%   - The default document type is ``A preliminary report''
%     The document type can be changed using the command \reporttype{}
%     There are some short-cuts for \reporttype{}:
%      * for a PhD thesis, specify \thesis
%      * for a M.Tech./M.Phil./M.Des./M.S. dissertation, specify \dissertation
%      * for a DIIT/B.Tech./M.Sc.project report, specify \project
%      * for a preliminary report, specify \prelim
%   - once the above are defined, use \maketitle to generate the titlepage
