Efficient directory names

[e-lo]

As a programatic user, I'd like to more efficiently navigate the GMNS spec directory and not worry about fussy capitalization.

If approved by community, I (@e-lo) am happy to implement.

Proposed solution

Adopt following folder structure:

spec\
examples\ #small network examples dir...without stray .csvs in base dir
usage\ #example validation and usage notebooks, currently in validation tools and conversion tools dir
docs\ 
  spec\ # all markdown versions of spec
  img\  # all image files

[e-lo]

Note that this structure will also more effectively support a future site with automated documentation generation.

cc: @joecastiglione on if community would like me to implement.

Thank you for the suggestion. Other users, notably AequilibraE, are using the current directory structure in some examples. I am fine with this change, but would like to save it for the next release, with advance notification to the user community.

Excellent suggestion

Let's do it, starting with the development (soon to be develop) branch.

Done in the development branch. Now need to check for and fix broken links.
Conversion_Tools -> usage\conversion
Images -> docs\img
Small_Network_Examples -> examples
Specification -> spec
Specification_md -> docs\spec
Validation_Tools -> usage\validation
