profile -- profile a computation

Description

Running a computation with the profile keyword enables the Macaulay2 profiler, which measures and stores the frequency of particular instructions for aid in analyzing and optimizing the computation.

i1 : profile matrix table(4, 5, (i,j) -> i^j)

o1 = | 1 0 0 0  0  |
     | 1 1 1 1  1  |
     | 1 2 4 8  16 |
     | 1 3 9 27 81 |

              4       5
o1 : Matrix ZZ  <-- ZZ

Afterwards, running profileSummary and coverageSummary produces easy to read tables summarizing the accumulated data so far in different ways.
