Reading and writing of DXF files.
This class can read in a DXF file and calls methods from the interface DL_EntityContainer to add the entities to the contianer provided by the user of the library.
It can also be used to write DXF files to a certain extent.
When saving entities, special values for colors and linetypes can be used:
Special colors are 0 (=BYBLOCK) and 256 (=BYLAYER). Special linetypes are "BYLAYER" and "BYBLOCK".

reads the next couplet in the file.
