release: update version number to 1.3.1 (#504)

match nodes containing int/float/nan/inf metric values (#349)

fix query matcher code v1.3.0 to handle matching nodes:
- with metric values containing a combination of ints, floats, NaN, and inf
  values (e.g., match nodes with time > 5, where time values may be an int,
  float, NaN, or inf)
- with metric value of NaN (e.g., match nodes with time == NaN)
- with metric value of inf (e.g., match nodes with time == inf)

add tests for using the query language and standard filter functions to
match nodes with NaN and inf metric values

update CHANGELOG for v1.2.0 release (#200)

- update version throughout code
- update docs with updated tree API
- add query language basics to docs

increment minor version --> 1.1.0
