Add learning objectives for Procedural Programming

[steve-crouch]

There are no learning objectives for the Procedural Programming lesson, so a suggested set are:

• Variables
  • Describe the fundamental types of variables.
  • Assign values to basic variables and make use of them.
  • Print the content of variables.
• Containers
  • Use container-type variables to hold multiple sets of data.
  • Use indexing and other access methods to access data within containers.
  • Differentiate between mutable and immutable variable types.
• Functions
  • Define a function that takes parameters.
  • Return a value from a function.
  • Test and debug a function.
  • Set default values for function parameters.
  • Explain why we should divide programs into small, single-purpose functions.
