    * G-API: First steps with tutorial
    
    * G-API Tutorial: First iteration
    
    * G-API port of anisotropic image segmentation tutorial;
    * Currently works via OpenCV only;
    * Some new kernels have been required.
    
    * G-API Tutorial: added chapters on execution code, inspection, and profiling
    
    * G-API Tutorial: make Fluid kernel headers public
    
    For some reason, these headers were not moved to the public
    headers subtree during the initial development. Somehow it even
    worked for the existing workloads.
    
    * G-API Tutorial: Fix a couple of issues found during the work
    
    * Introduced Phase & Sqrt kernels, OCV & Fluid versions
    * Extended GKernelPackage to allow kernel removal & policies on include()
    
    All the above stuff needs to be tested, tests will be added later
    
    * G-API Tutorial: added chapter on running Fluid backend
    
    * G-API Tutorial: fix a number of issues in the text
    
    * G-API Tutorial - some final updates
    
    - Fixed post-merge issues after Sobel kernel renaming;
    - Simplified G-API code a little bit;
    - Put a conclusion note in text.
    
    * G-API Tutorial - fix build issues in test/perf targets
    
    Public headers were refactored but tests suites were not updated in time
    
    * G-API Tutorial: Added tests & reference docs on new kernels
    
    * Phase
    * Sqrt
    
    * G-API Tutorial: added link to the tutorial from the main module doc
    
    * G-API Tutorial: Added tests on new GKernelPackage functionality
    
    * G-API Tutorial: Extended InRange tests to cover 32F
    
    * G-API Tutorial: Misc fixes
    
    * Avoid building examples when gapi module is not there
    * Added a volatile API disclaimer to G-API root documentation page
    
    * G-API Tutorial: Fix perf tests build issue
    
    This change came from master where Fluid kernels are still used
    incorrectly.
    
    * G-API Tutorial: Fixed channels support in Sqrt/Phase fluid kernels
    
    Extended tests to cover this case
    
    * G-API Tutorial: Fix text problems found on team review
