* Performance optimized version of ToNumber
Approximately 5x faster for floats (data dependent)
and about the same speed for integers.
- Instead of blindly trying to parse as Long, do a quick check
for obvious problems (e.g. decimal point).
- Don't trim. It's already done by called methods.
- Use valueOf() instead of parse() to avoid object creation
* Add Java Microbenchmark Harness
The shaded JAR is missing the OpenRefine classes, for a reason
that I haven't figured out, so requires openrefine-main.jar at runtime.
* Remove old implementations of ToNumber
* Remove unneeded dependencies from main project
* Clean up and reformat
