OpCodes base module

This module implements part of the data structures which define the cluster operations - the so-called opcodes.

Every operation which modifies the cluster state is expressed via opcodes.

Class	`BaseOpCode`	A simple serializable object.
Function	`BuildJobDepCheck`	Builds check for job dependencies (`DEPEND_ATTR`).
Function	`NameToReasonSrc`	Convert an opcode class name to a source string for the reason trail
Constant	`COMMENT_ATTR`	Undocumented
Constant	`DEPEND_ATTR`	Undocumented
Constant	`SUMMARY_PREFIX`	Undocumented
Variable	`TNoRelativeJobDependencies`	Undocumented
Class	`_AutoOpParamSlots`	Meta class for opcode definitions.
Function	`_NameComponents`	Split an opcode class name into its components
Function	`_NameToId`	Convert an opcode class name to an OP_ID.
Constant	`_OPID_RE`	Undocumented
