Fixed XSLT to properly generate getters / setters.
Fixed XSLT to properly generate getters / setters.

The template pattern for `INPUT` and `OUTPUT` fields that
would generate getters / setters where not matching correctly.

Pattern is `/PAP/VARIABLES/INPUT` where the actual path
is `/PAP/VARIABLES/INPUTS/INPUT` same story with
`/PAP/VARIABLES/OUTPUT` and `/PAP/VARIABLES/OUTPUTS/OUTPUT`.

Fixes issue #3.
