Bug: cactiStyle did not work well when there were no data

(cherry picked from commit 775ed726b8da7b50c2ccff628d9b396a9a6eaeab)
Merged pull request #111 from wfarr/customizable-divisors

Make y axis divisors configurable
Add docs, menu item for yDivisor along with cleanup
added pathExpression to timeFunction to allow calculations
Add the special pattern "<...>" for use in the target pattern.
This corresponds to a match-all up to an arbitrary depth.
This is equivalent to the * wildcard character zero or more times.
E.g. a.b.<...>.c.d will match a.b.c.d, a.b.1.c.d, a.b.c.1.2.3.c.d, etc.
The '%l' datetime formatting option is not supported on Windows. We can use '%I' instead. The only difference is that it always uses 2 digits for the time (e.g. 06AM instead of 6AM)
Use native path separator.
