Config parser module

[Larry Bates]

ConfigParser is for parsing configuration files of the format:

[section1]
option1=<information>
option2=<information>
.
.
.
optionN=<information>

[section2]
option1=<information>
option2=<information>
.
.
.
optionN=<informattion>

Your data doesn't fit that format.

Looks to me like you should write a small class object for
each different type of record that can be found in the file
that knows how to parse that record and put the information
from that record in to class attributes for easy access.

Something like:

class gridclass:
    def __init__(self, recordToParse):
        elements=recordToParse.split(' ')
	self.type=elements[0]
        self.pointId=int(elements[1])
        self.coordinateSysNo=float(elements[2])
        self.x=float(elements[3])
        self.y=float(elements[4])
        self.z=int(elements[5])
	

Then read the lines, determine the line type and create a class
instance for each one.
