Extension of GA (pyrobot/brain/ga.py)

Classes
`Environment`	Class to hold environment information.
`GPGene`
`GPTree`	Main tree structure for GP.
`Operator`	Class to hold operator information.

Function Summary
	`and_func(operands, env)` Special form (lazy evaluation) for short-circuiting 'and'.
	`div_func(*operands)` For protected division.
	`ifpos_func(operands, env)` Special form (lazy evaluation) for if-positive.
	`or_func(operands, env)` Special form (lazy evaluation) for short-circuiting 'or'.
	`parse(exp, objType)` Parser to turn "(+ 4 5)" into a GPTree expression.
	`wrapObj(current_symbol, objType)` A wrapper for parse.

Function Details

Special form (lazy evaluation) for short-circuiting 'and'. Needs env.

For protected division. type="regular" so no environment is passed.

Special form (lazy evaluation) for if-positive. Needs env.

Special form (lazy evaluation) for short-circuiting 'or'. Needs env.

Parser to turn "(+ 4 5)" into a GPTree expression.

A wrapper for parse. Should have been recursive...
