There were problems with reading multiple small chunks from matix file. Therefore there will be synchronization of that.

*Changed error message in src/rawop.cpp

Added constructor that support single file parameter
This is for the cases when user would like to write to existing file
Copy and swap

Technique from https://www.gniibe.org/memo/software/git/using-submodule.html
Improve experience for http protocol users that does not have a keypair on the server to use git protocol

Add classes to simpler parsing of CT regression arguments

Fix previous implementation

*Arguments reporting possibility from program startLog

Making some fields in DenFrame2DReader protected to be accessible to its child class DenFrame2DReaderItk

*Improved program reporting of the time

DenFrame2DReader is able to internally keep multiple buffer copies

Added an extension to a DEN format, where the sizes of dimensions might be uint32_t instead of uint16_t
File is in a DEN extended format if the first 6 bytes are zero
Next four bytes are uint32_t dimy
Next four bytes are uint32_t dimx
Next four bytes are uint32_t dimz

Improved paths for the test
Testing of I/O DenFileInfo and DenFile2DReader

New functions to test existing directory and regular file added
isDirectory
isRegularFile

Second constructor fix

Class to get information about executable path

Improvement of construction and destruction of some objects

This class uses #include <mutex>

Added #include <experimental/filesystem> that is part of C++ 17 spec.
In C++ 13 it is however possible to link against libstdc++fs.a library using directive link_libraries(stdc++fs)
