planned user interaction during macro playback

[westram]

Motivation:

Often it would be useful, if a macro could be interrupted at some planned point and the could be prompted to e.g.

• edit some value in an input field,
• mark targeted species

or take other similar action.

Proposed implementation:

To allow interaction the macro calls a perl sub named notify_and_wait().

• the sub displays custom text passed as parameter (telling the macro- what to do).
• it has a button Continue macro execution. After pressing that button, the tool will terminate and
• the macro execution will continue.

To ease the programming of interaction in macros

• the macro window in ARB_NTREE gets a button User interact, which
• opens a prompt asking for the above-mentioned custom text and
• after pressing ok, inserts the appropriate call into the currently recorded macro.
