1. deleting empty keywords in *CONTROL - done
2. deleting referred entities
3. when repeated cards are there like elements, then the first card stores the names of fields to save memory. if latter cards have more fields, then names of those fields are not available. this is causing problems in GUI because, in GUI the values are associated to the field names. Example - 3cars_shell2_150ms.k, *ELEMENT_SEATBELT_ACCELEROMETER
4. Don't export the end cards which are blank
5. If kw has _TITLE the respective html file has to be modified for TITLE card
