MeasurementReceived method description is reformatted to be more
readable and consistent with other API documents.
Special values for Exponent and Mantissa fields specify now only NaN
value as this is only special value defined by HTS specification for
measurement.
This patch updates Thermometer API document to reflect changes in
Thermometer interface and introduction of ThermometerManager
interface and fixes minor formatiing inconsistencies.
According to HTS 1.0 (Table 3.1, and Sections 3.1.1.4 and 3.2), the
Temperature Type Characteristic is optional. The only restriction is
that it shall not be present if the Temperature Type is non-static, for
which case the "Temperature Type" field shall be present on the
Temperature Measurement Characteristic value.
Given there is no default value specified when the Temperature Type is
static and unknown, the "Type" entry for MeasurementReceived() on the
Thermometer API was made optional.
