Removed all std::unary_function classes
Issue/feature addressed
std::unary_functions are deprecated from C++-11 and removed in C++-17 (see https://en.cppreference.com/w/cpp/utility/functional/unary_function). In our current minimum requirements of C++-14 the compiler ignores this base class, but as we intend to move to C++-17 having them will create errors. On newer versions of clang and gcc they already throw warnings when using C++-14.
Proposed solution
Remove all the std::unaray_function decelerations from the code.
Implementation
See above.
Tests
No new tests required.
Notes
Validated with local ctest that removing the declerations has not broken anything (as expected).

Warning
On the 19.07 the code formatting (code style) was standardised using clang-format, over the whole Nektar++ code. This means changes in your branch will conflict with formatting changes on the master
branch. To resolve these conflicts , see
