HEADER section : contains the settings of variables associated with the drawing.
Section fully supported (all the variables are parsed and stored)
CLASSES section : holds the information for application-defined classes whose instances appear in the BLOCKS, ENTITIES, and OBJECTS sections of the database.
Section not supported (nothing interesting)
TABLES section : contains several tables, each of which can contain variable number of entries.
APPID not used parsed parsing is not perfect
BLOCK_RECORD not used parsed
DIMSTYLE not used parsed
LAYER used parsed
LSTYLE not used parsed parsing is not perfect
STYLE used parsed UCS not used parsed parsing is not perfect
VIEW not used parsed parsing is not perfect VPORT not used parsed
