//! This class allows the definition of groups
//! of primitives inside of graphic objects (presentations).
//! A group contains the primitives and attributes
//! for which the range is limited to this group.
//! The primitives of a group can be globally suppressed.
//!
//! There are two main group usage models:
//!
//! 1) Non-modifiable, or unbounded, group ('black box').
//! Developers can repeat a sequence of
//! SetPrimitivesAspect() with AddPrimitiveArray() methods arbitrary number of times
//! to define arbitrary number of primitive "blocks" each having individual apect values.
//! Any modification of such a group is forbidden, as aspects and primitives are mixed
//! in memory without any high-level logical structure, and any modification is very likely to result
//! in corruption of the group internal data.
//! It is necessary to recreate such a group as a whole when some attribute should be changed.
//! (for example, in terms of AIS it is necessary to re-Compute() the whole presentation each time).
//! 2) Bounded group. Developers should specify the necessary group aspects with help of
//! SetGroupPrimitivesAspect() and then add primitives to the group.
//! Such a group have simplified organization in memory (a single block of attributes
//! followed by a block of primitives) and therefore it can be modified, if it is necessary to
//! change parameters of some aspect that has already been set, using methods:
//! IsGroupPrimitivesAspectSet() to detect which aspect was set for primitives;
//! GroupPrimitivesAspect() to read current aspect values
//! and SetGroupPrimitivesAspect() to set new values.
//!
//! Developers are strongly recommended to take all the above into account when filling Graphic3d_Group
//! with aspects and primitives and choose the group usage model beforehand out of application needs.
