Serialization and JSON representation

[tommyod]

@glemvik

• Added serialize and deserialize methods to exercises, days and program.
• Added to_dict to Program.

from streprogen import Program

# Create an 8-week program, rounding every exercise to nearest unit og 5kg
program = Program("My first program!", duration=2, units="kg", round_to=5)

with program.Day("Day A"):
    program.DynamicExercise("Bench press", start_weight=80, min_reps=3, max_reps=8)
    program.DynamicExercise("Squats", start_weight=100, min_reps=3, max_reps=8)

with program.Day("Day B"):
    program.DynamicExercise("Deadlifts", start_weight=100, min_reps=2, max_reps=7)
    program.StaticExercise("Curls", "3 x 10 @ 18kg")

# Render the program, then print it
program.render()

import json
print(json.dumps(program.to_dict(), indent=2, sort_keys=True))
