Project #2b - Genetic Program

For this subproject you will need to complete the GP including the following functionallity (in addition to the functions from the previous assignment):

• Add a conditional to the function set of the expression trees.
• Mutation
• Crossover of two trees
• Selection
• Elitism if you are using a generational model

Project Write-up: For this subproject you only need a description of the general algorithm: generational or steady-state, how mutation works, the selction mechanism, etc. and a description of any problems so far. Note that the write-up may be fairly short.
