v0.3.0 — IP Pool support + minor improvements

[eexit]

Hello,

• Added IP pool support + test
• Added comments
• Normalized PHP files with PHP-FIG recommendations + set a coding style consistency
• Minor improvements

Review will be easier when ignoring whitespace changes: https://github.com/sendgrid/smtpapi-php/pull/5/files?w=1

Would be really nice to have this merged asap.

Thank you very much,

[mbernier]

Should this have $GIT_VERSION ?

[eexit]

I have no idea, I didn't write this, I just changed the indentation :)

[mbernier]

Other than the question about $GIT_VERSION, the changes look legit.

Left to do:

• Confirm $GIT_VERSION question
• Test the changes

@mbernier I tested this PR in our system integration and it works perfectly. What else test would you like to be done?

Thanks for your review btw!

[mbernier]

We'll run it through our internal tests as soon as we can and then hopefully get it merged.

[eexit]

Oh, right! Great!

Thanks :)

Thanks so much for the PR!

What did you use to lint the codebase for FIG standards?

[eexit]

@eddiezane Thanks!
I quickly did it by hand... However, there are some PHP beautifuler online but I never tested yet :)
