Tom Ice 2cc5cae1a8 Changed non-interactive args and fixed main loop
* The previous commands were Lower CamelCase style and had no equivalent
  short options. If you wanted to see the branch tree via non-interactive
  mode, you always needed to supply "branchTree" as the passing argument to
  the git-quick-stats script.

  This commit changes the argument style to be more akin to the POSIX and GNU
  styles of arguments commonly seen in many other applications. As of this
  commit, there is no compatibility with legacy commands, so those who have
  been using the old commands will unfortunately need to get familiar with the
  new ones. All documentation and tests have been updated accordingly to
  reflect the new changes.

* The main interactive loop contained a non-variable constant that was only
  getting parsed correctly due to legacy fallback behavior. This commit fixes
  the main loop and cleans up the formatting a little bit.

* Added -r to more areas where read reads in a variable to help prevent
  it from mangling backslashes.

* Changed everything to use bash's built-in [[ notation and did some minor
  formatting changes to reduce the LOC.

* Removed some unnecessary echo statements and did some other minor cleanup.

> `git quick-stats` is a simple and efficient way to access various statistics in git repository.
> Any git repository contains tons of information about commits, contributors, and files. Extracting this information is not always trivial, mostly because of a gadzillion options to a gadzillion git commands I dont think there is a single person alive who knows them all. Probably not even [Linus Torvalds](https://github.com/torvalds) himself :).

#### Git log since / until
You can set variable `_GIT_SINCE`, `_GIT_UNTIL` and limit the git log
```bash
export _GIT_SINCE="2017-20-01"
export _GIT_UNTIL="2017-22-01"
```
then run `git quick-stats` (affect all stats, except "My daily status" and "Git changelogs" )
#### Git log limit
You can set variable `_GIT_LIMIT` for limited output (it will affect: "Git changelogs" and "Branch tree view" )
```bash
export _GIT_LIMIT=20
```
#### Git pathspec
You can exclude directory from the stats by using [pathspec](https://git-scm.com/docs/gitglossary#gitglossary-aiddefpathspecapathspec)
```bash
export _GIT_PATHSPEC=':!directory'
```

## FAQ
*Q:* I get some errors after run git-quick-stats in cygwin like `/usr/local/bin/git-quick-stats: line 2: $'\r': command not found`
*A:* You can run dos2unix app in cygwin `/bin/dos2unix.exe /usr/local/bin/git-quick-stats`. This will convert it to Unix format and you then should be able to run it.
## Contribution
Want to contribute? Great! First, read this page.
#### Code reviews
All submissions, including submissions by project members, require review.</br>
We use Github pull requests for this purpose.
#### Some tips for good pull requests:
* Use our code </br>
When in doubt, try to stay true to the existing code of the project.
* Write a descriptive commit message. What problem are you solving and what
are the consequences? Where and what did you test? Some good tips:
[here](http://robots.thoughtbot.com/5-useful-tips-for-a-better-commit-message)
and [here](https://www.kernel.org/doc/Documentation/SubmittingPatches).
* If your PR consists of multiple commits which are successive improvements /
fixes to your first commit, consider squashing them into a single commit
(`git rebase -i`) such that your PR is a single commit on top of the current
HEAD. This make reviewing the code so much easier, and our history more
readable.
#### Formatting
This documentation is written using standard [markdown syntax](https://help.github.com/articles/markdown-basics/). Please submit your changes using the same syntax.
