Removed need to input pop number and hap number

I simplified the input format requirements. The user no longer has to input the number of populations and haplotypes on the first line.

Skeleton of data input working

I got a skeleton of the data input working this week. Basically, the input text field is just a large textarea form field. Then I use a php script to parse out the variables, then use the javascript code I used before to generate the map pies. Data input could certainly be cleaned up, but this was just so I could learn one way of passing data from page to page (through form variables).
