Mostly moving existing content around with a few exceptions. I'm removing Java-specific nomenclature in a lot of parts.

Current Element index File contains:

1. Finding Element examples
2. Element Information examples

• I moved Finding Element examples to new finders.md
• I moved Element information examples to information.md
• I added Is Visible and Attributes and Properties placeholder sections to information.md

Current Relative Locators File contains:

1. Different finding element code examples
2. Tips for using locators
3. Traditional locator table
4. Relative locator examples

• I renamed the file to just locators.md to focus exclusively on those
• I merged finding element code into finders.md, and in the process I pretty much completely rewrote it with a better html example
• I moved the tips into the "Encouraged Test Practices" section and linked to it
• I updated relative locator examples to only show working with locators (no find element calls, no importing libraries, etc) The goal is going to be to have a full code example somewhere that we can link to, in the meantime this removes extraneous code that isn't what the article is focused on.
• Added relative locator chaining example
