Feature request: Read one input file at a time

[GoogleCodeExporter]

What steps will reproduce the problem?

I am encountering problems with getting the Columbia, SC network into NEXTA.  I 
have used TransCAD to prepare the input_node.csv, input_link.csv, 
input_zone.csv, and input_demand.csv.  At this point, I would like to be able 
to read each input file one at a time.  That is, I would to be able to first 
import the input_node.csv and see the nodes on the GUI, then import 
input_link.csv, etc.  This way I can see where the error may be.  With the 
current capability, I first create a an blank project file to have NEXTA create 
the input files for me.  Then, I modify these input files by copy-and-paste 
values into them.  When there is a problem with these files, which is the case 
for me, NEXTA crashes.

What is the expected output? What do you see instead?

What version of the product are you using? On what operating system?

Please provide any additional information below.

The safest way is to use an Excel file to store node, link, and demand file 
(just like NEXTA 2 does), and important the excel table directly. CSV files 
have been difficult to change, as Excel always locks csv files, and provide 
confusing messages when saving in CSV format.
