Factorization using the elliptic curve method (ECM)
---------------------------------------------------
Each section below named EXPR profiles 10 invocations of
  factor -v --ecm-primes - 'EXPR'
Each invocation generates a line of results with the following fields:
- Total time spent
- Peak memory usage
- Number of primes used
- Number of curve points used
