Planet Class

Today I worked on the Planet object class. Wasted HOURS writing out long
if else and switch statements because each solar zone holds different
climates at different probabilities, and each climate holds resources at
different probabilities as well. But finally realized I could put the
distributions into 2D arrays and then simply reference a list of strings
afterwards in a print method!
