Provide clear reference to neural-fortran

[nedtaylor]

This issue can include a list of files where inspiration has been taken (or neural-fortran has been used as a template) for procedures and modules.

Feel free to comment here with files that need correct attributing.

Files requiring clear attributing:

• [x] example/simple/src/main.f90
• [x] example/sine/src/main.f90
• [x] get_numparams* procedure
• [x] getparams* procedure
• [x] setparams* procedure
• [x] getgradients* procedure
• [x] setgradients* procedure
• [x] getoutput* procedure
• [x] src/lib/mod_optimiser.f90 module

Files where attributing needs to be discussed (these are not copies of neural-fortran, but concepts may be shared):

• [ ] input layers
• [ ] flatten layers

@milancurcic, here is an open issue with files and procedures that I know need clear attribution to neural-fortran. The examples should already include a print statement, but providing a link to neural-fortran seems necessary also.

As for the get and set procedures of the base_layer_type (and any child type), my plan is to include an attributing statement at the top of each of the files they are defined in and then just above the relevant procedure.

As of commit 70b345238c40ef975b9051e3cd65185f07290603, attribution statements have now been included in all the files listed above.
