[DLAB3DEV-15] Create a mapper

Xslt-mapping-generator project with basic functionality:

• create xslt that transform dlibra record to fbc record with given tags

On input we have two maps:

• First one is map of (dlibraTagName -> fbcTagName) every tag of dlibra has it's fbc format and map create relations between them.
• Second one is map of (xmlns:namespaceName -> namespaceLink) for adding namespaces when user define tags with specific namespaces.

Logic validate inputs (avoids duplicates of fbc tags, check if namespace is defined by user if tag with unknown namespace is defined)

Output is string with xslt based on template_fbc file with edited or added user tags.
