-\b NOTE: In order to take into account any possible distortion of a shape 
-that affects the resulting bounding box, the algorithm enlarges 
-the bounding box to the value of the maximum deflection value of 
-faces (by iterating through all faces of a shape).
-This functionallity is implemented in such a way in order to have 
-satisfactory performance.

-\anchor check_compound_anchor
-<br><h2>Check compound of blocks</h2>
-
-\n Checks whether a shape is a compound of glued blocks. To be
-considered as a compound of blocks, the given shape must satisfy the
-following conditions:
-<ul>

-\n <b>TUI Command:</b>
-<em>geompy.CheckCompoundOfBlocks(Compound).</em> Checks if the shape

-<br><h2>Detect Self-intersections</h2>
-
-\n Checks the topology of the selected shape to detect self-intersections.
- Returns True if there are no self-intersections. Reports pairs of
- intersected sub-shapes, if there are any.
-
-\note This tool is useful for detection of shapes, not suitable for
-arguments of Boolean operations and Partition algorithm.
