// 
// Dynamic interactions base, including macros.
// 
// To put existing interactions on other NPCs, most recompiled animations use special blending techniques
// so interactions meant for one NPC (like Alyx) could transition into a more appropriate animation for another NPC.
// Unfortunately, there does not appear to be a way to transition dynamically to a NPC's current weapon's aiming animation
// without rewriting a great portion of the dynamic interaction code.
// So, in order to determine which animation to blend from/into, global variables are declared before $including these QCIs:
// 
// Blend_SMD_Default - Their most common aiming anim. For example, citizens use the SMG aim while metrocops use the Pistol aim.
// Blend_SMD_Pistol - Pistol aiming animation.
// Blend_SMD_Rifle - SMG/AR2 aiming animation.
// 
// These are then called by each interaction based on which one they used to begin with.
// For example, DI_Idle_Pistol is used for Alyx's pistol interactions while DI_Idle_Rifle is used for Alyx's shotgun interactions.
// 
// This technique is now used with other animation ports as well.
// 
	
// This is the macro that makes the blended animation.
// Activity and stuff should be added with $append.
// This can be used with both dealing and receiving ends of the interaction.
