* Logger: Rename logger to Logger from dLogger * Logger: Add compile time filename Fix include issues Add writers Add macros Add macro to force compilation * Logger: Replace calls with macros Allows for filename and line number to be logged * Logger: Add comments and remove extra define Logger: Replace with unique_ptr also flush console at exit. regular file writer should be flushed on file close. Logger: Remove constexpr on variable * Logger: Simplify code * Update Logger.cpp
