-Integrate can have its own set of rules for specific integrals, which

-for the integral requested. If this is the case, the anti-derivative

 expression is returned unsimplified.

 General structure
 ^^^^^^^^^^^^^^^^^
 
-The integration starts at the function {Integrate}, but the task is
-delegated to other functions, one after the other.  Each function can
-deem the integral unsolvable, and thus return the integral
-unevaluated. These different functions offer hooks for adding new
-types of integrals to be handled.

 Expression clean-up
 ^^^^^^^^^^^^^^^^^^^
 
 Integration starts by first cleaning up the expression, by calling
-{TrigSimpCombine} to simplify expressions containing multiplications
-of trigonometric functions into additions of trigonometric functions
-(for which the integration rules are trivial), and then passing the
-result to {Simplify}.
