Edit for Markdown Format

Hi all,
The collaborative_tools_ms.md is now formatted for mark down. So next we'll fill in the bullet points with text. Remember that each sentence should be in its own line for optimum commit history. I am hoping to have a go at the Introduction tomorrow after afternoon. This will be my contribution for the week as I'll not be at lab meeting this week. My apologies for double booking the Science Communication workshop with lab meeting.
