Problems with empty PRODUCT_DEFINITION() #7
Description
There seem to be STEP-Files that have an empty name in their PRODUCT_DEFINITION()'s. The parser currently only looks at the name inside PRODUCT_DEFINITION so in such cases, we get empty strings as component names.
The STEP-files without name in PRODUCT_DEFINITION refer to a PRODUCT_DEFINITION_FORMATION_WITH_SPECIFIED_SOURCE which itself refers to a line containing "PRODUCT()".
To get the real component names, the parser has to follow these extra references.
