/**
* 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".
