Create fields data structure

[elizabethburgessamt]

Make a structure of a field to plant crops. Different variations to be discussed below.

So far, we have discussed 3 different field layouts:

• First is a 13x13 grid consisting of a scarecrow, 4 large sprinklers, and 8 small sprinklers. This consists of 156 spaces for crops.
• Next is a 6x39 plot with 26 small sprinklers for a total of 208 spaces for crops. Scarecrows will be placed outside of the planting area, and they can cover a second plot of the same size.
• Last is a 6x39 plot with no sprinklers for a total of 234 spaces for crops. While not having sprinklers gives more space for planting, the player loses the convenience of automation and will have to spend time manually watering the plot.

We need an interface to support the different fields. They each need a value for crop capacity and a count of how many trellis crops it can support

I changed the interface to an abstract class per Commit 89b9bdd.

For the 3 discussed layouts, I've figured out the maximum trellis crop count. Since these are constant amounts, they won't really need to be set save for initialization. Diagrams showing the layout will be posted soon.

• The 13 x 13 grid has a combination of sprinklers and a scarecrow to work around. In order to get proper paths to use all of the spaces for other crops, I've found that the maximum count is 91.
• The 6 x 39 sprinkler grid needs more access points to crops to get around the sprinklers. The current count is 134.
• The 6 x 39 no sprinkler grid consists of two rows on both lengths plus an access path down the center with some crops in the path. This number came out to 170.

At this point, it makes sense to start issues to create classes for each field unless we're going to do some polymorphism thing.
