Create a lesson about Strings

[aromeronavia]

Great @pjhampton! I bet functional programming have helped you a lot with your project 😛

Of course! Let's just split the lesson into sections and then we can start to work :)

@doomspork @pjhampton
I propose this sections for the lesson:

1. Strings in Elixir: Explain what's the deal with strings in Elixir, about their binary-ty and stuff haha

• Graphemes
• Codepoints

2. Common functions:

• downcase/uppercase
• length
• split
• at
• contains
• to_char_list (this is gonna be interesting...)

3. String manipulation

• iterate a string
• replace characters

4. A simple exercise:
   I have two exercises in mind.
   • Check if two words are anagrams (kinda easy)
   • Check if a word is a palindrome (harder)

I just have this at the moment, let's fulfill the lesson! :)

Great idea, @setzer777! And thanks for the suggestion.

I am currently working on an Elixir Natural Language Processing library as part of my PhD (it's currently private on my github) and I have been looking into this for quite sometime.

Maybe we could work together on this lesson together?

PR #224 was merged today. I think this issue can be closed now.
