'''

parseDXFtext(file_name) - 'file_name' is the name of the DXF file to parse.

The function returns a list of text strings.

sumStuds(textList) - Summarize the stud counts found in the argument list

Stud count string format: [36] or [14,2,2,14]

Example usage:

file_name = r'C:\SDS2_7.0\macro\New Versions\Ref\plan.dxf'

stud_count = sumStuds(parseDXFtext(file_name))

Version 1.01 (6/27/07)

Version 1.02 (12/21/07) Modify parseDXFtext to read 2000 version DXF files

*** WATCH OUT FOR MEMBER NUMBERS IN PLACE OF PIECEMARKS ***

Member numbers begin with an open bracket '['
