ENH: support for "hash" function in more recent version of Octave

ENH: Add minimal classdef support for MOcovMFile …

Avoid prepending `mocov_line_covered` to:

- `classdef`;
- `properties` and `methods` section opening statements;
- inside the entire `properties` section, since a limited subset of the
  M-file syntax is allowed.

be included in the coverage report.

Closes #4.

ENH: mocov_find_files.m Add exclude patterns option …

Will exclude matching directories and files from the list.

BUG: Fix coverage calculation for empty files …

For files with no executable lines, the coverage report should
have a nominal 100% coverage rate. This is the behaviour of other
coverage packages, such as those for Python.

Previously, files without any executable lines would report a
coverage of "NaN%", due to the division by 0.

MAINT: Change denumerator->denominator …

"Denominator" is the correct English name for the bottom part of
a fraction.
