### Decimal numbers rounding

You may find fails likes this one when you run the tests:

```
-----  String filters for compound values of attributes: string match  -----
(qfilters_and_compounds_deeper.test) output not as expected
VALIDATION ERROR: input line:
                           "f": 3.1400000000000001,
does not match ref line:
                           "f": 3.14,
```

This is not an actual problem with the test or Orion, but a rounding problem in the version of the json module that 
comes with Python 2.6 (the testHarness.sh program typically uses `python -mjson.tool` to beutify responses).

The solution is easy: don't use Python 2.6. The recommended version is Python 2.7. Note that CentOS 6 comes with Python 2.6 at
system level, but you can use [virtualenv](https://virtualenv.pypa.io/en/stable/) to use Python 2.7 in a easy way.
