Typos and mistakes in Notebook #1

[Haksell]

I am scared of using git with notebooks, so I'm just going to post them here.

Typos:

• the concent of using IPython Notebeoks
• When you see a MethodError, it's a huge clue that you are (finishes in the middle of the sentence)
• resahpe
• evaluetes
• defintion

Mistakes:

• In "An Overloaded Function Koan", returns are reversed (Float64 returns 0 and Int64 returns 1)
• and their second dimension equal to 4. (third)
• We can create random arrays using the zeros or ones function (We can't)
• The struct in the last koan is useless and quite confusing. Why not just @test c == 55?
