timenorm-1.0.3

This release includes some improvements in the linking process in the scala version of the parser, especially for the Between operator:

• linking of the Between operator has been improved checking the text and the position with respect to the child entity. E.g. "until 2019" cannot be linked with End-Interval.
• Unknown is now the default value for Type property if the case is not found in date-types.txt
• For Frequency the value of the Type operator is Other.
• date-types.txt has been refined removing unnecessary cases and adding new ones like hours, seconds,...

In parseBatchToXML the text is cleaned replacing one control characters with one space character to avoid wrong spans when the text contains consecutive control characters (^C, ^L, ...). Previously, consecutive control characters were replaced with a single space character.
