should the makefile headers have the same license text as the other files from hipdnn?

Thanks for pointing this out, I believe the hipdnn source files should have the same license text as the makefile and others as that's what's used across the entire repo. I'll update this shortly

[adeljo-amd]

Updated so all the files now use the same license text

There seems to be some issue with fused_conv_fprop_activ on the tarball path that can also be observed in the rocm-libraries folder too - the wheel path passes though

New examples are missing .gitignore file. Otherwise LGTM
