Move Variable Declarations from main to inputs

The following are all defined in the main. I want to move them to inputs and call them as global variables. real(real12), allocatable :: T(:,:,:), TN(:,:,:), Told(:,:,:) real(real12), allocatable :: TD(:), TPD(:) !1 (merged)D x and b respectively This is where the majority of our code wide variables are defined and maintaining this across all such variables. Additionally, we should keep the main clear of clutter such as the allocates which then could be moved to Initiate or set_global_variables.
